  • Soda Can Calorimeter
    Soda Can Calorimeter Energy Content of Food SCIENTIFIC SCIENCEFAX! Introduction Have you ever noticed the nutrition label located on the packaging of the food you buy? One of the first things listed on the label are the calories per serving. How is the calorie content of food determined? This activity will introduce the concept of calorimetry and investigate the caloric content of snack foods. Concepts •Calorimetry • Conservation of energy • First law of thermodynamics Background The law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another. This fundamental law was used by scientists to derive new laws in the field of thermodynamics—the study of heat energy, temperature, and heat transfer. The First Law of Thermodynamics states that the heat energy lost by one body is gained by another body. Heat is the energy that is transferred between objects when there is a difference in temperature. Objects contain heat as a result of the small, rapid motion (vibrations, rotational motion, electron spin, etc.) that all atoms experience. The temperature of an object is an indirect measurement of its heat. Particles in a hot object exhibit more rapid motion than particles in a colder object. When a hot and cold object are placed in contact with one another, the faster moving particles in the hot object will begin to bump into the slower moving particles in the colder object making them move faster (vice versa, the faster particles will then move slower). Eventually, the two objects will reach the same equilibrium temperature—the initially cold object will now be warmer, and the initially hot object will now be cooler.

  • Adiabatic Dewar Calorimeter
    I.CHEM.E. SYMPOSIUM SERIES NO. 97 ADIABATIC DEWAR CALORIMETER T.K.Wright'and R.L.Rogers* A simple calorimeter has been developed that enables chemical reaction runaway conditions to be directly determined, under the low heat loss conditions found in full scale chemical plants. Since the calorimeter provides temperature time data in the near absence of environmental heat losses the data can be simply analysed to yield heats of reaction and chemical power output. The latter are used either in conjunction with plant natural cooling data to assess reactor stability or at higher temperatures to size reactor vents. If the reaction mechanisms are known or adequate assumptions can be made then the temperature-time data can also be processed to yield reaction kinetics constants for simulation purposes. Keywords: Hazards, Exotherms, Adiabatic Calorimeter, kinetics INTRODUCTION Evaluation of chemical reaction hazards requires the detection of exotherms/gas generation likely to lead to reactor overpressure. Some form of small scale scanning calorimetry is generally used for the initial detection of the exotherm and gas generation and a temperature of onset will be determined which is dependent on the sensitivity of the equipment, but on a 10-20gm scale exothermlcity will generally be detected at self heating rates of 2-10°C/hr - approximately 3-10 watts/lit. Depending on apparent exotherm size and proximity to process temperature or any likely excursions then secondary testing may be required to display more accurately (a) The minimum temperature above which the reactor will be unstable on the scale used. (b) The consequences of the exotherm - heat of reaction/adiabatic rise/ pressure developed/venting requirement.

  • The Measurement of Heat Release Rates by Oxygen Consumption Calorimetry in Fires Under Suppression
    The Measurement of Heat Release Rates by Oxygen Consumption Calorimetry in Fires Under Suppression BOGDAN Z. DLUGOGORSKI, JACK R. MAWHINNEY and VO HUU DUC National Research Counc~l,Institute for Research in Construction Ottawa, Ontario KIA OR6, Canada ABSTRACT A series of open-space fire experiments was conducted at the National Fire Laboratory (NFL) to validate the capabilities of the NFL room-size oxygen-consumption calorimeter, and to assess the importance of accounting for actual water vapour content in the exhaust gases in calculating heat release rates (HRR). Water spray was used to partially suppress some of the fires, and to add significantly to the humidity of the exhaust gases. The equations normally used in the fire research community for oxygen calorimeter assume unsuppressed fires, and that water vapour in the exhaust gases is due solely to the humidity of the incoming air and to combustion reactions. This paper derives the basic equations for computing heat release rates based on the principle of nitrogen balance. The general equations take into account all sources of water vapour, including incoming air, combustion reactions, and evaporation due to suppression. The equations are then simplified to i) neglect all humidity, and, ii) consider only the humidity of the incoming air. The predictions of the HRR from the three sets of equations are compared with the HRR calculated for unsuppressed fires and with the HRR obtained by measuring fuel consumption rates. As long as the water vapour content in the exhaust gases is less than 7 %, both simplified equations can be used to measure the HRR of partially suppressed fires, without significant error.

  • Calorimetry Lab
    P31220 lab Calorimetry Lab Purpose: Students will measure latent heat and specific heat. PLEASE READ the entire handout before starting. You won’t know what to do unless you understand how it works! Introduction: Calorimetry is the art of measuring energy. For example, determining how many calories are in a cheeseburger is done with a device called a “bomb calorimeter.” A sample of the food is burned in a closed container that is surrounded by water. The energy content of the food is determined from the temperature increase of the water jacket that surrounds the combustion chamber. In this lab, you will do two classic calorimetry experiments: measuring the latent heat of fusion of water, and measuring the specific heat capacities of two different metals. Both experiments will use the same apparatus. Apparatus: Fig. 1 shows the construction of the basic calorimeter. The calorimeter is designed to minimize heat flow between the inner cup and the outside world. Conduction of heat is eliminated by supporting the inner cup only by the thin, insulating phenolic (a type of plastic) ring, and by providing an insulating air space around the cup. Convection is eliminated by blocking air circulation with the solid ring and the lid. Radiation is eliminated by making the inner cup and outer jacket out of aluminum, which is mirror- bright to infrared radiation. Fig. 1: The calorimeter. To use the calorimeter, the inner cup is half filled with a known mass of water, and the temperature is measured. The sample is added, the temperature is measured again, and the desired quantity (latent heat or specific heat) is calculated.

  • Technology Data Sheet Nuclear Material (NM)
    IPNDV Working Group 3: Technical Challenges and Solutions Nuclear Material (1)—Technology Data Sheet September 14, 2016 Nuclear Material (NM) Technology Name: Calorimetry Physical Principle/Methodology of Technology: Calorimetry measures the thermal power output of heat-producing NM. The heat results from the radioactive decay of isotopes by alpha particle emission (for most Pu isotopes and 241Am) and by beta decay (for 241Pu and Tritium). 239Pu for instance decays to 235U with the emission of an alpha particle and releasing 5.15 MeV in energy. The energy loss through the emission of spontaneous fission neutrons on the other hand is many orders of magnitude smaller than the total disintegration of energy and loss due to gamma ray emission, representing only a small percent of the total disintegration energy of Pu isotopes. Calorimetry is most commonly used for Pu measurements due to the high heat output of most Pu isotopes. In addition, the build-up of 241Am as Pu ages significantly increases the power output. It is also possible to measure highly enriched uranium (HEU) when there is a high enough 234U content. For reference, isotopes that emit relatively large amounts of heat include 238Pu (560 W/kg), 239Pu (1.9 W/kg), 240Pu (6.8 W/kg), 241Pu (4.2 W/kg), 241Am (114 W/kg), and 234U (0.2 W/kg). Thermal powers ranging from 0.1 mW to 1000 W can be measured with calorimetry. Used independently, calorimetry confirms that an item emits heat and determines how much heat is being emitted. The heat measurement is very accurate and precise.

  • Draft Atmospheric Pressure Effects on Cryogenic
    DRAFT ATMOSPHERIC PRESSURE EFFECTS ON CRYOGENIC STORAGE TANK BOIL-OFF J. P. Sassa and C. R. Fortier1' aNASA Kennedy Space Center, KT-E Kennedy Space Center, FL, 32899, USA "NASA Kennedy Space Center, NIE-F7 Kennedy Space Center, FL, 32899, USA ABSTRACT The Cryogenics Test Laboratory (CTL) at the Kennedy Space Center (KSC) routinely utilizes cryostat test hardware to evaluate comparative and absolute thermal conductivities of a wide array of insulation systems. The test method is based on measurement of the flow rate of gas evolved due to evaporative boil-off of a cryogenic liquid. The gas flow rate typically stabilizes after a period of a couple of hours to a couple of days, depending upon the test setup. The stable flow rate value is then used to calculate the thermal conductivity for the insulation system being tested. The latest set of identical cryostats, 1 000-L spherical tanks, exhibited different behavior. On a macro level, the flow rate did stabilize after a couple of days; however the stable flow rate was oscillatory with peak to peak amplitude of up to 25 percent of the nominal value. The period of the oscillation was consistently 12 hours. The source of the oscillation has been traced to variations in atmospheric pressure due to atmospheric tides similar to oceanic tides. This paper will present analysis of this phenomenon, including a calculation that explains why other cryostats are not affected by it. INTRODUCTION Cryostats are regularly used at the CTL to determine the thermal performance of various insulations. Tests are conducted in small 1O-L cylindrical cryostats or large 1000-L spherical tanks.
