Consider the following fluids, each with a velocity of V = 5 m/s and a temperature of T inf = 20°C, in cross flow over a 10 mm diameter cylinder maintained at 50°C: atmospheric i) air, ii) saturated water, and iii) engine oil.

A) Calculate the rate of heat transfer per unit length, q′, using the Churchill–Bernstein correlation.

B) Generate a plot of q′ as a function of fluid velocity for 0.5 ≤ V ≤ 10 m/s.
