Answer to Question #327701 in Mechanical Engineering for Jhonny

Question

22. A coil has an inlet temperature of 50 oF and outlet of 85 oF. If the mean temperature of coil is 100 oF, find

the bypass factor of the coil. (SHOW THE SOLUTION)

A. 0.4 B. 2 C. 1.667 D. 0.3

Answer 1

For heating coil t₃ < t₂ < t₁

t₁ = 50

t₂ = 85

t₃ = 100

BPF = (t₃ - t₂) / (t₃ - t₁ ) = (100 - 85) / (100 - 50) = 0.3
