Btu Calculator Water
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.
Btu calculator water. The british thermal unit or btu is an energy unit. Carlson heat exchanger calculator for determining btu for a given flow rate. Btu 60 minutes per hour 8 345404 lbs per gallon of water specific heat specific gravity delta t. Calculate your room s btu requirement.
First mark the calculated pump pressure on the left side of the pump curve where the feet of head pressure is found. Outdoor temperatures external walls insulation heated adjacent rooms i e. A btu is a relatively small amount of energy. In recent years the scientific industry contexts is more commonly replacing this unit of measure by the si unit of energy.
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. Please note this is a guide only. 1btu hour is equal to 0 293 watt. The formula would be 90 feet x 1 5 x 04 5 4 feet of head.
What is a btu. 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. 1 btu 1 055 joules 252 calories 0 293 watt hour or the energy released by burning one match. About equivalent to the heat generated by striking 1 stick match.
Enter your room details below along with a name and save it to your wish list to keep it for easy reference. 1 watt is approximately 3 412 btu per hour. This is the standard measurement of heat output needed to heat any structure therefore can measure radiator power. Only input whole numbers do not use a comma or point.
Once you have calculated the pump pressure you can use the pump curve to plot pump gpm. You can calculate btu heating or cooling requirements for your. One is roughly equal to 1 055 joules. A btu describes the energy content or heat value of fuels.
This calculator can only gauge rough estimates. 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. A radiator with insufficient output may never raise the temperature to that required. Btu calculator btu formulas for water circulating heat transfer.
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. A btu or british thermal unit is a unit of energy. Above below and to the side all play a part. You can then filter.
A british thermal unit btu is the measure of energy required to heat 1 pound of water 1 degree fahrenheit. The amount of btus given a specific flow rate and delta t.
