Description: Performance of heat exchangers using epsilon-NTU relations.

Equations/Symbols:

Calculate:
Insert heat exchager type, hot fluid inlet temperature (Th,in), cold fluid inlet temperature (Tc,in), UA product (UA), hot fluid mass flow (mh), cold fluid mass flow (mh), hot fluid specific heat (cp,h), cold fluid specific heat (cp,h) and press 'Calculate'.
Heat exchanger type: Th,in (K): Tc,in (K): UA (W/K): mh (kg/s): mc (kg/s): cp,h (J/(kg.K)): cp,c (J/(kg.K)):
Fluid properties:
cp,h=4,180.00 J/(kg.K)
cp,c=4,180.00 J/(kg.K)
