Question:-
A heat exchanger with heat transfer surface area A and overall heat transfer coefficient U handles two fluids of heat capacities C1 and C2 such that C1 > C2. The NTU of the heat exchanger is given by
Option (A)
AU/C2
Option (B)
e-(AU/C2)
Option(C)
e-(AU/C1)
Option(D)
AU/C1
Correct Option:
(A)
Question Solution:
NTU = (UA/Cmin) (C2 < C1) = (UA/C2)
