Enter the mass flow rate, specific heat, and change in temperature into the calculator to determine the heat load.

## 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.

## FAQ

**What is a heat load?**
