Very closely related to this is the units ofpowerwhich is the energy used per unit of time. For the above, the units of power are BTU / hr or kW (kilowatts) which is the same as kWh / hr. We might say an AC is rated to be 1.5 kW, meaning it uses 1.5 kW per hour. So in...
How Many CFM Per Square Foot One of the most common questions is how many CFM airflow do we need per sq ft. Obviously, that depends on the ceiling height and ACH. If we predispose 8 ft ceiling height, we can calculate CFM per sq ft for different values of ACH: ...
How much heat is required to raise the temperature of an object with a heat capacity of 3.4 j / k from 17.34 k to 67.18 k? Explain how to convert 6.60 x 1010 joules to British thermal units (Btu). Calculate the quantity of heat required to raise the temperature of 40.0 g of water ...
and amps and watts change. Splicing extension cord might work; it’s really hard to know for sure, however. 12K DIY model has max. wattage of 960W (based on 12.5 EER rating) and max. cooling amperage of 15A. 300W is a bit low; at 300W, you would be getting about 3,750 BTU cool...
How many kilograms are there in an imperial ton? A city that uses ten billion Btu's of energy each month is using how many kilowatt-hours of energy? A heat pump requires 350 W of electrical power to deliver heat to your house at a rate of 2440 J per second. How many joules of ene...

Calculate the total potential energy, in Btu, of an object that is 20 ft below a datum level at a location where g = 31.7 ft/s2 and which has a mass of 100 lbm. What is the coefficient of friction? The Nusselt number? For a flow over a prescribed...
While you sleep, your body is using energy at a rate of 77 W. How many food calories are used during an eight hour period? One food calorie is equal to 4186 joules. A 30.0 W light bulb is 19.0 percent efficient. This means ...
