Consider the following fluids, each with a velocity of V

Consider the following fluids, each with a velocity of V = 5 m/s and a temperature of Try; = 20°C, in cross flow over a 10-mm diameter cylinder maintained at 50°C: atmospheric air, saturated water, and 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.
