1 BTU needed to raise or lower 1degree F of 1 lb water
i think exponents? remember, PEMDAS?
HVAC Load Calculation is a formula used by a contractor salesmen that determines the proper tonnage size of heating and cooling systems to be installed in Residential or Commercial applications. The formula is used to calculate the total cooling and heating BTU'S (British Thermal Units) for the proper values of determining the correct tonnage to be installed in HVAC applications. Tonnage is the size of the HVAC system. Without this Load calculation the wrong tonnage could be installed and it causing to much humidity in the summer in cooling season and not enough heating in the winter season. Also the HVAC system may never stop running to reach the proper temperature that the thermostat is set for. Thus causing high electricity out of pocket cost.
Heptane has the chemical formula of C7H16. It has a BTU rating of 19,163 BTU per pound and a rating of 4,465.8 kilojoules per mole.
To convert CFH to BTU, you need to use the formula 1 CFH which is equivalent to 1000 BTUs.
12000 btu howmany kw?
The formula for this question is ... horse power = btu / 2545 Therefore 1 / 2545 = .0003929 hp
The BTU output requirements of your furnace must be determined by heat load and heat loss calculations on the area that is heated. You should consult several HVAC contractors for estimates and recommendations.There are many factors that influence the BTU requirements of a furnace in any location.
To convert wet BTUs to dry BTUs, you need to account for the moisture content in the wet BTU measurement. This is done by subtracting the energy associated with the water content from the total wet BTU value. The formula is: Dry BTU = Wet BTU - (Moisture content percentage × Wet BTU). This conversion provides a more accurate representation of the energy content of the fuel without the influence of water.
The number of BTUs required to heat a room over 100 degrees would depend on factors such as the size of the room, insulation, outside temperature, and desired indoor temperature. To calculate the exact BTU requirement, you would typically need to know the specific details of the room and use a heating load calculation formula.
Formula for what?!
The formula is simple. One ton of cooling equals 12000 btu. So a three ton A/C has a 36000 btu capacity.
Divide the heat loss or gain obtained by the load calculation by square footage of the building.
