Consider Problem 10.41 In an effort to increase the condensation rate an engineer proposes to apply a L = 100μm thick Teflon coating to the exterior surface of the brass tube to promote drop wise condensation. Estimate the new condensation convection coefficient and the steam condensation rate per unit length of the tube after application of the coating. Comment on the proposed scheme's effect on the condensation rate (the condensation rate per unit length in Problem 10.41 is approximately 1 x 10-3 kg/s).
