Btu calculator water. Only input whole numbers do not use a comma or point. A btu describes the energy content or heat value of fuels. A btu or british thermal unit is a unit of energy. Please note this is a guide only.

A btu is a relatively small amount of energy. Outdoor temperatures external walls insulation heated adjacent rooms i e. In recent years the scientific industry contexts is more commonly replacing this unit of measure by the si unit of energy. The calculators assume 100 efficiency and no loss of energy during the heating process.

Calculate your room s btu requirement. You can then filter. The calculators support celcius centigrade fahrenheit watts w kilowatts kw btuh joule british termal unit btu liter gallon kg lb cubic inch cubic foot etc. 1 watt is approximately 3 412 btu per hour.

A british thermal unit btu is the measure of energy required to heat 1 pound of water 1 degree fahrenheit. Online water specific heat calculator the calculator below can be used to calculate the liquid water specific heat at constant volum or constant pressure and given temperatures. Btu 60 minutes per hour 8 345404 lbs per gallon of water specific heat specific gravity delta t. You can calculate btu heating or cooling requirements for your.

A radiator with insufficient output may never raise the temperature to that required. About equivalent to the heat generated by striking 1 stick match. One is roughly equal to 1 055 joules. Carlson heat exchanger calculator for determining btu for a given flow rate.

A btu is an abbreviation for b ritish t hermal u nit which is the amount of energy required to raise 1 pound of water 1 degree fahrenheit at sea level. Once you have calculated the pump pressure you can use the pump curve to plot pump gpm. Enter your room details below along with a name and save it to your wish list to keep it for easy reference. The amount of energy that is needed to either cool or heat one pound of liquid water one degree fahrenheit at a constant pressure of one atmosphere.

The british thermal unit or btu is an energy unit. What is a btu. The amount of btus given a specific flow rate and delta t. Our btu calculator is the best on the web as it accurately determines the number of btus your radiator should have in order to effectively and efficiently heat your room.

The formula would be 90 feet x 1 5 x 04 5 4 feet of head. This is the standard measurement of heat output needed to heat any structure therefore can measure radiator power. First mark the calculated pump pressure on the left side of the pump curve where the feet of head pressure is found. The output specific heat is given as kj kmol k kj kg k kwh kg k kcal kg k btu it mol r and btu it lb m r.

This calculator can only gauge rough estimates. Btu calculator btu formulas for water circulating heat transfer.
