The heat transfer coefficient of a steel (k = 43 W/m · K) tube
(1.9 cm ID and 2.3 cm OD) in a shell-and-tube heat exchanger is 500
W/m2 · K on the inside and 120 W/m2 · K on the shell side, and it
has a deposit with a total fouling factor of 0.000176 m2 · K/W.
Calculate
a. The overall heat transfer coefficient
b. The cleanliness factor, and percent over surface.
