Question:-
The equation of effectiveness e = 1 –e-NTU of a heat exchanger is valid (NTU is number of transfer unit) in the case of
Option (A)
Boiler and condenser for parallel flow
Option (B)
Boiler and condenser for counter flow
Option(C)
Boiler and condenser for both parallel flow and counter flow
Option(D)
Gas turbine for both parallel flow and counter flow
Correct Option:
(C)
Question Solution:
Heat capacity ratio C will be same for both evaporator and condenser
C = O
Î = 1-e-NTU
This is valid for both evaporator and condenser
