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

Equations/Symbols:

Calculate:
Insert heat exchager type, hot fluid inlet temperature (T_h,in), cold fluid inlet temperature (T_c,in), exchanged heat (q), hot fluid mass flow (m_h), cold fluid mass flow (m_h), hot fluid specific heat (c_p,h), cold fluid specific heat (c_p,h) and press 'Calculate'.

Heat exchanger type: 1. Parallel 2. Counter flow 3. Cr=0 4. Shell and tube - one shell pass 5. Cross flow 1pass - cmax mixed 6. Cross flow 1pass - cmin mixed T_h,in (K): T_c,in (K): q (W): m_h (kg/s): m_c (kg/s): c_p,h (J/(kg.K)): c_p,c (J/(kg.K)):

Fluid properties: cp,h=4,180.00 J/(kg.K) cp,c=4,180.00 J/(kg.K)	Dimensionless numbers ε=0.299 NTU=0.433 Cr=0.833	Sizing parameters UA=1,811.73 W/K Th,out=334.45 K Tc,out=310.96 K
