Difference Between BTU and Watts Key Difference - BTU Vs Watts
Difference Between BTU and Watts www.differencebetween.com Key Difference - BTU vs Watts It is first important to identify the concepts of energy and power in order to understand the difference between BTU and Watts. If an object is doing a work, the object is given an amount of energy to perform the task. If there is a heat transfer from or to an object, an amount of energy is removed from or given to the said object. The rate of work done or the rate of the heat transfer is defined as power. BTU and Watt are two different types of measurement units to measure the energy transfer and power, respectively. Thus, the key difference between BTU and Watts is that BTU measures energy, which is a stand-alone physical property whereas Watts measures the rate of transfer of energy that is always associated with a time factor. What is BTU? BTU is the abbreviated form for British Thermal Unit. The term thermal is often used for measuring thermal energy or the energy in the form of heat. BTU is not a part of the International System of Units or SI units. But it is often used as a measurement in heating and air-conditioning industry even at present. One BTU is defined as the amount of heat that should be transferred to one pound (lb) of water to raise its temperature by one degree of Fahrenheit (F). Since lb and F are both conventional units, the BTU can be identified by its SI units’ counterpart, Joule (J). That is, one joule is the heat required to transfer to one gram of water to raise the temperature by one degree Celsius (C). -

Syllabus Section I Power Market Restructuring: Current Context and Historical Events ** Important Acknowledgement: These notes are an edited abridged version of a set of on-line lecture notes prepared by Professor Tom Overbye, ECpE, University of Illinois, 2008 Last Revised: 9/13/2011 Setting Course Topics in Context EE/Econ 458 focuses on the restructuring of wholesale power markets, using the U.S. as the primary source of illustrations. Particular attention will be focused on U.S. restructuring efforts in the Midwest (MISO), New England (ISO-NE), New York (NYISO), mid- Atlantic States (PJM), California (CAISO), Texas (ERCOT), and the Southwest Power Pool (SPP). First, however, it is important to consider this restructuring movement within the larger context of the energy delivery system as a whole. Electric Systems in Energy Context Electricity is used primarily as a means for energy transportation. – Other sources of energy are used to create it, and once created it is usually converted into other forms of energy before actual use. About 40% of US energy is transported in electric form. Concerns about CO2 emissions and the depletion of fossil fuels are becoming main drivers for change in the world energy infrastructure. Measurement of Power Power: Instantaneous consumption of energy Power Units Watts (W) = voltage times current for DC systems kW – 1 x 103 Watts MW – 1 x 106 Watts GW – 1 x 109 Watts Installed U.S. generation capacity is about 900 GW ( about 3 kW per person) Measurement of Energy Energy: Integration of power over time; energy is what people really want from a power system Energy Units: Joule = 1 Watt-second (J) kWh – Kilowatt-hour (3.6 x 106 J) Btu – 1054.85 J (British Thermal Unit) Note on Unit Conversion: 3413 Btu ≈ 1 kWh Annual U.S. -

CAPACITY One Gallon Split Into Fourths Is Four Quarts
CAPACITY One gallon split into fourths is four quarts. Take that and divide by two and you got a pint. NAME: Split that pint up into halves and make a cup, DATE: and that cup will fit eight fluid ounces inside of it. One gallon is four quarts (or eight pints, or sixteen cups)! One quart is two pints (or four cups, or thirty-two fluid ounces)! WATCH VIDEO One pint is two cups (or sixteen fluid ounces)! One cup is eight fluid ounces! A gallon of milk split in fourths makes four quarts. Split a quart of milk in half; then a pint is what you’ll have, which can make two cups you see often when you drink your school milk carton. If you can drink the milk in eight sips, each is about an ounce going through your lips! Volume is a word that’s familiar, and capacity and volume are similar; and though it’s easy to assume, capacity’s not exactly volume. Capacity’s how much something can hold; the amount is always the same. Volume’s the measure of what’s inside, and that amount can change.

Water System Operator's Guide
MATH REVIEW For a rectangular tank: Most math problems a water treatment plant To find the capacity of a rectangular or square operator solves requires plugging numbers into tank: formulas and calculating the answer. When working with formulas, here are some simple Multiply length (L) by width (W) to get area (A). rules to follow. • Work from left to right. Multiply area by height (H) to get volume (V). • Do anything in parenthesis first. Multiply volume by 7.48 gallons per cubic foot to get capacity (C). • Do multiplication and division in the numerator (above the line) and in the A = L x W denominator (below the line), then do V = A x H addition and subtraction in the numerator C = V x 7.48 and denominator. • Divide the numerator by the denominator Find the capacity of a rectangular tank 15 feet (ft) last. long, 12 ft wide, and 10 ft high: Volume A = 15 ft x 12 ft = 180 square feet (ft2) The volume of a tank in cubic feet is equal to V = 180 ft2 x 10 ft = 1,800 cubic feet (ft3) the tank area multiplied by the tank height. The C = 1,800 ft3 x 7.48 gal/ft3 =13,464 gal capacity in gallons is equal to the volume in cubic feet multiplied by 7.48 gallons per cubic foot. For a circular tank: Area (A) = (3.14) x diameter squared (D2) / divided by 4 Volume (V) = A x H Capacity (C) = V x 7.48 gal/ft3 A = [ x (D2)/4] V = A x H C = V x 7.48 49 Find the capacity of a circular tank with a For an oval tank: diameter of 15 ft and a height of 12 ft: To find the gallons in an oval tank: A = [3.14 x (15 ft2)/4] = 177 ft2 Multiply the height by width by (3.14) divided by 4 to get the area of the oval.
