What is the correct answer?


In a forced draft cooling tower, water is cooled from 95 to 80°F by exposure to air with a wet bulb temperature of 70°F. In this case, the

A. Range is 15°F

B. Approach is 10°F

C. Both (A) & (B)

D. Neither (A) nor (B)

Correct Answer :

C. Both (A) & (B)

Temperature range (T1 - T2) = 15°F
Temperature approach (T2 - tw) = 10°F
Wet-bulb temperature tw = 70°F
