Consider the following fluids, each with a velocity of V = 5 m/s and a temperature of T inf = 20โ, in cross flow over a 10 mm diameter cylinder maintained at 50โ: atmospheric i) air, ii) saturated water, and iii) engine oil. A) Calculate the rate of heat transfer per unit length, qโฒ, using the ChurchillโBernstein correlation. B) Generate a plot of qโฒ as a function of fluid velocity for 0.5 โค V โค 10 m/s.
