LMTD in case of counter flow heat exchanger as compared to parallel flow heat exchanger is
A. Higher
B. Lower
C. Same
D. Depends on the area of heat exchanger
Answer: Option A
Solution (By Examveda Team)
Counter flow heat exchangers are inherently more efficient than parallel flow heat exchangers because they create a more uniform temperature difference between the fluids, over the entire length of the fluid path.This Question Belongs to Mechanical Engineering >> Heat And Mass Transfer
The heat transfer increases when attaching fins to a surface due to increase in the: (a) convection coefficient (b) surface area (c) surface temperature (d) conduction coefficient
