Hi, I'm working on a project for which I need to heat air and feed it into the intake valve of an engine. I need to heat room temperature air to 45 degrees Celsius quickly enough to feed it 500-1200 ft/minute through an intake tube with diameter of 2.75 in. My pump must be able to do this for up to two hours at a time.

BTU stands for British Thermal Unit. It is the industry standard unit of measurement for heat quantity. 1 BTU is the amount of heat required to raise the temperature of one pound of water at its maximum density by 1 degree Fahrenheit:

A WATT is the unit for measuring electrical power, i.e., the rate of doing work, in moving electrons by, or against, an electrical potential. Formula: Watts = Amperes x Volts.(Return to Top)

Good question. The answer can be different depending on which manufacturer you ask. Technically, a Watt is the unit of power that was created by James Watt, the inventor of the Steam Engine, over 200 years ago. It is equal to 1 / 765 of a horsepower. This can be converted to electrical power using some intense math that we can skip for now. But you can get an idea about it if you consider a washing machine with a ? horsepower motor. It will take about 380 Watts of electricity to drive it.

It's important to understand energy use in lamps when you choose from today's full array of lighting technologies. The amount of light given off is measured in lumens. One lumen is the equivalent of the light given off by one candle. A watt, on the other hand, is the amount of electricity a light bulb uses to produce light - it's not an indication of brightness.

A British Thermal Unit is the amount of heat required to raise the temperature of one pound of water one degree Fahrenheit.

BTU's (British Thermal Units) are a standard of measurement which represent the heat value of any type of energy used to create heat. The amount of fuel that a fireplace will consume per hour is calculated with the BTU value of the fuel it uses to determine the input of that fireplace. BTU values of any type of energy are determined by the actual amount of heat required to increase the temperature of one pound of water, by one degree Fahrenheit.
