Mass Flow Calculator
Use the calculator below to determine the required flow rate in a heating system. To use, simply enter the heat requirement in the text input box and adjust the slider to the required temperature differential.
Please note that Java must be enabled on your browser in order to use this calculator. Java is available from here.
The volumetric flow rate in heating systems is expressed as:
- Q is the volumetric flow rate
- h is the heat flow
- cp is the specific heat capacity of the liquid
- ρ is the density of the liquid
- ΔT is the temperature differential
