There are 7.48 gallons in The science of hydraulics is as old as civilization itself. a cubic foot, with each gallon weighing approximately For centuries, engineers have succeeded in making water 8.34 pounds, so 7.48 gal x 8.34 lbs/gal = 62.4 pounds. flow from one place to another with as few hitches as possible.

  • Pressure Dependence of Senseair´S NDIR Sensors
    Pressures Dependence of SenseAir´s NDIR sensors Pressure Dependence of SenseAir´s NDIR sensors Pressure affects the reading of CO 2 sensors. This is because of the physics principle used to measure CO 2 concentration. The NDIR type of sensors measure the IR radiation absorbed by CO 2 molecules, which corresponds to the mole concentration. And when pressure increases, the number of molecules in a given volume also increases linearly. Therefore, all CO 2 sensors have a dependence on pressure. How atmosphere affects the reading of CO 2 Regulation by using ABC function sensors? SenseAir sensors make use of the ABC algorithm to The composition of air is unchanged until an elevation of compensate for any long-term drift due to e.g. aging of approximately 10.000 m, but the atmospheric pressure of components and initial inaccuracy due to e.g. air varies with altitude, that at high altitudes there’s lower transportation. If we located a CO 2 at 2000 m, as figure 2 pressure than at sea level. This means also that the shows, using Senseair’s ABC function can effectively number of molecules per volume unit decreases, adjust the reading close to true reading which minimizes according to the Ideal gas law. the difference generated by pressure sensitivity. Since an NDIR sensor in fact measures the number of molecules per volume unit, it will show a lower reading at higher altitudes. But the unit used by the sensor to express CO 2 concentration is ppm by volume and the volume fraction occupied by CO 2 is the same regardless of pressure, which means that the choice of ppm by volume as unit of measurement for CO 2 sensors introduces a deviation that can be compensated for, if needed.

  • EPA Requirements & Refrigerant Handling
    Course 5: EPA Requirements & Refrigerant Handling November 4 & 6, 2014 1 Federal Clean Air Act (sc. 608) All persons who maintain, service, repair, or dispose of appliances that contain regulated refrigerants, be cerGfied in proper refrigerant handling techniques. If EPA regulaons change aer a technician becomes cerGfied, it is the responsibility of the technician to comply with any future changes. 2 Technician Certification 4 Categories of Technician Cer1ficaon Type I: Persons who maintain, service or repair small appliances must be cerGfied as Type I technicians. Type II: Persons, who maintain, service, repair or dispose of high or very high-pressure appliances, except small appliances and motor vehicle air condiGoning systems, must be cerGfied as Type II technicians. 3 Technician Certification (cont.) 4 Categories of Technician Cer1ficaon Type III: Persons, who maintain, service, repair, or dispose of low-pressure appliances must be cerGfied as Type III technicians. Type IV (Universal): Persons, who maintain, service or repair both low and high-pressure equipment, as well as small appliances, must be cerGfied as Universal technicians. 4 Refrigeration Definition Heat is a form of energy. Refrigeraon is the movement of heat from an area where it is not wanted to an area where it is less objecGonable. For example, a refrigerator removes heat from the inside of the cabinet and transfers it to the outside. 5 Gauge Manifold Set One of the most important tools to the HVAC&R technician is the gauge manifold set. The compound gauge (BLUE) and the high pressure gauge (RED) are connected to the manifold, and the manifold is then connected by hoses to access ports to measure system pressures.

  • Pressure Washing Terminology Acronyms
    Pressure Washing Terminology Acronyms: DS - Downstreaming GPM – Gallons per minute PSI – Pound Per Square Inch SH - Sodium hypochlorite Chemicals: Sodium hypochlorite is a chemical compound with the formula NaClO. It is composed of a sodium cation (Na+) and a hypochlorite anion (ClO−); it may also be viewed as the sodium salt of hypochlorous acid. When dissolved in water it is commonly known as bleach or liquid bleach, and is frequently used as a disinfectant or a bleaching agent. Sodium hydroxide, also known as caustic soda, or lye, is an inorganic compound with the chemical formula NaOH. It is a white solid and highly caustic metallic base and alkali salt which is available in pellets, flakes, granules, and as prepared solutions at a number of different concentrations. Sodium hydroxide forms an approximately 50% (by weight) saturated solution with water. Glossary: Downstreaming - Downstream injecting just means that you introduce an additional liquid, such as a detergent, into your power washer through an injector that is mounted after the pump into the high pressure line side. This is usually done in low pressure mode. If you want to do a little high pressure mode injecting in your power washer, you will need an injector designed to operate at high pressures. You'll be happy to know that some of these high pressure injectors can be temporarily installed on the end of your gun lance. Emulsion – A mixture of two or more liquids that are normally immiscible (nonmixable or unblendable). Gallons Per Minute – A measurement of how many gallons of liquid can be supplied through the water pump and a pressure washer.

  • Chapter 7. Units and Measurements the SI System (Système International D’Unités) of Reporting Measurements Is Required in All ASA, CSSA, and SSSA Publications
    Chapter 7. Units and Measurements The SI system (Système International d’Unités) of reporting measurements is required in all ASA, CSSA, and SSSA publications. Other units may be reported parenthetically if this will clarify interpretation of the data. The National Institute of Standards and Technology maintains online resources for SI (http://physics.nist.gov/cuu/) and has published a comprehensive guide (Thompson & Taylor, 2008) that includes a concise checklist of style requirements. Table 7–6 at the end of this chapter gives selected conversion factors. BASE AND DERIVED UNITS The SI system is based on seven base units (Table 7–1). Derived units (Table 7–2) are expressed algebraically in terms of the base units. Some of these have been given special names and symbols, which may be used to express still other derived units. An example of a derived unit with a special name is the newton (N) for force; the newton is expressed in basic units as m kg s−1. Another unit with a special name is the pascal (Pa), which is one newton per square meter. Using SI Units Publications of ASA, CSSA, and SSSA impose less-stringent requirements in style than the full formal SI system as published by the National Institute of Standards and Technology (Thompson & Taylor, 2008; Taylor & Thompson, 2008), and new develop- ments in SI may take time to win adoption by the editorial boards. For example, this style manual allows molar concentration but disallows normal concentration, whereas strict SI usage declares both to be obsolete (Thompson & Taylor, 2008, 8.6.5).

  • Fundamentals of Pressure and Temperature Measurement
    Fundamentals of Pressure and Temperature Measurement Jeff Goetzman CenterPoint Energy. 1111 Louisiana Houston, Texas 77002 Our Gauge Pressure (psig) is the gas The correct measuring of Pressure and pressure we read on the meter with an Temperature is one of the most important accurate gauge. For our example we will elements in the accurate measurement of use the common residential delivery Natural Gas. The basic principles were pressure of .25 psi. established many years ago by two men, Robert Boyle an Anglo Irish philosopher, Calculation at .25 psig chemist, and physicist and Jacques Charles, a French Inventor, scientist and Now let’s plug our numbers into our formula: mathematician. Fp = (.25psig+14.7atm) / 14.95base Since we are discussing Fundamentals we will try to keep it as simple possible. For this example the answer would be 1.0. Therefore anytime we measure at these Boyles Law factors we can just simply read the meter index difference as the volume. In 1662 Robert Boyle first published what today is known as Boyles Law. This law can Calculation at 5.0 psig be simply stated as: For a fixed amount of ideal gas kept at a fixed temperature, In this example we will keep everything Pressure [P] and Volume [V] are inversely constant except pressure. Let’s say the proportional. So as pressure is raised more customer called and need more pressure for gas can occupy the same space. a new pool heater or standby generator they installed. As a result a Service Tech was Simple Pressure Factor dispatched and raised the pressure on the meter to 5.0 psig.
