Head Load Formula
The following formula is used to calculate a heat load.
Q = MF * CP * T
- Where Q is the heat load (kW)
- MF is the mass flow rate (kg/s)
- CP is the specific heat (kJ/kg)
- T is the change in temperature (K or C)
Heat Load Definition
A heat load is defined as the total energy that is extracted from an area in order to keep the temperature constant.
Heat Load Example
How to calculate heat load?
- First, determine the mass flow rate.
For this example, it’s found that the mass flow rate is 20 kg/s.
- Next, determine the specific heat.
The specific heat of the gas in the area is found to be 40 kJ/kg.
- Next, determine the change in temperature.
After a certain amount of time, the temperature changes to 10 C.
- Finally, calculate the heat load.
Using the formula we find the heat load to be 20*40*10 = 8,000 kW.
A heat load is the amount of energy that needs to be extracted from a given area to keep the space within a certain temperature range.
