I have an open drum filled with water, 100lt and heating with a LP gas burner. How do I calculate the BTU hr heating the water to say 100 C I need a safety tilting valve to cut off the gas flow...
A British thermal unit (BTU) is defined as the amount of heat required to raise the temperature of 1 pound of water by 1 degree Fahrenheit. To calculate the temperature of a water sample from the BTUs applied to it, you must know the weight of the water and its starting temperature. Y...
BTU, or the British Thermal Unit, is the amount of heat required to raise one pound of water one degree Fahrenheit. The British Thermal Unit measures the amount of heat, or thermal energy. Temperature is the level rather than amount of heat. Therefore, there is no formula to convert a Br...
CFM Calculation:Airflow has to be strong enough to change the complete volume of 300 sq ft room (with 8 sq ft ceiling height) 2 times per hour. Volume of a room = 300 sq ft x 8 ft = 2,400 ft3. To change it 2 times per hour (ACH = 2), we need to deliver 4,800 ft3per ...
Here's a general calculation you can start with to get a baselineBritish thermal unit(Btu) cooling size: (Room square footage x 20) + (IT equipment watt usage x 3.14) + (Active people in the room x 400) But this is just a starting point. If you want a more accurate estimate and ...
A room air conditioner's efficiency is measured by the energy efficiency ratio (EER). The EER isthe ratio of the cooling capacity (in British thermal units [Btu] per hour) to the power input (in watts). The higher the EER rating, the more efficient the air conditioner. ...
