It is important to note that water and LPG (propane) have different conversion formulas because they have different density. Maps by energy source and topic, includes forecast maps. Formula: Hr = P / (c * p * (t2 - t1)) Hr - heating rate P - power c - heat capacity p - density t1 - initial temperature t2 - final temperature We've been calculating it as follows and need to know if we're in the ballpark. WebThe calculator provides indicative conversion of gas consumption in cubic metres to kilowatt-hours and other units. Also, you can change the power unit from kW to HP. Switching your gas, electricity or water supplier doesn't have to be a headache - at least, not with Guild Energy. A solar energy water buffer tank with 200 US gallons is heated 200oF. Some of this electricity is used, in turn, to produce fresh For imperial meters, the reading is in hundreds of cubic feet (100 ft), so if your meter shows a usage of 1, you've actually used 100 ft. Subscribe to feeds for updates on EIA products including Today in Energy and What's New. WebPump Power calculation Formula: Pump power P (kW) in kilowatts is equal to the product of the rate of flow q (m 3 /hr) in cubic meter per hour, fluid density (kg/m 3) in kilogram per cubic meter, gravity g in m 2 /s, pump differential h (m) head in meter and the differential pressure p (Pa) in Pascal or N/m 2 divided by 36,00,000..
