Consider the following fluids, each with a velocity of V = 4 m/s and a temperature of T[infinity] = 20⁰ C, n cross flow over a 10-mm-diameter cylinder maintained at 50⁰ C atmospheric air, saturated water, and engine oil. (a) Calculate the rate of heat transfer per unit length, q', using the Churchill–Bernstein correlation, in W/m.
q'ₐᵢᵣ = ___________ W/m
q'ₐₜₑᵣ = ____________ W/m
q'ₒᵢₗ = _______________ W/m
