Heat exchanger power

Heat exchanger power

Heat exchanger power

(OP)
Hello,

I have no experience with the calculation of heat exchangers, but I need to know the nessecary power (in kW) of a heat exchanger fed with plant steam and heating up softened water with the following conditions :
flow : 4 m³/h
Tin : 10 °C
Tout : 60 °C

Can somebody give some formula's ?

THX,
Bert.

RE: Heat exchanger power

The formula you want:

Q = m Cp dT

m is the flowrate, kg/sec
Cp is the heat capacity, about 4.2 kJ/kgC
dT is the temperature change of the water, deg C

Q is then the heat load, kJ/sec or kW.
