Theory of flow through valves and fittings
Calculation of the flow for the thermal transfer
Flow in pipes and valves theory - full content
The flow rate of fluid required for the thermal energy transfer can be calculated as:
where is:
- q - flow rate [m3/h]
- &rho - density of fluid [kg/m3]
- c - specific heat of fluid [kJ/kgK]
- &Delta T - temperature difference [K]
- P - power [kW]
This relation can be used to calculate required flow rate of, for example, water heated in the boiler, if the power of
boiler is known. In that case temperature difference in above equation is the change of temperature of fluid in front and
after the boiler. It should be said that efficiency coefficient should be included in above equation, for precise calculation.
