Heat Transfer - Engineering

Q1:

LMTD correction factor which is to be applied for a cross-flow heat exchanger increases with increase in the number of shell passes. Its value for a single pass cross flow heat exchanger is

A 0

B 1

C >1

D <1

ANS:D - <1

The Logarithmic Mean Temperature Difference (LMTD) correction factor for a cross-flow heat exchanger increases with an increase in the number of shell passes. For a single pass cross flow heat exchanger, the LMTD correction factor is 1. So, the correct answer is: "1"
