Reconsider Prob. 10–65. Using EES (or other) software, investigate the effects of plate temperature and the angle of the plate from the vertical on the average heat transfer coefficient and the rate at which the condensate drips off. Let the plate temperature vary from 40°C to 90°C and the plate angle from 0° to 60°. Plot the heat transfer coefficient and the rate at which the condensate drips off as functions of the plate temperature and the tilt angle, and discuss the results.

Data from problem 65

Saturated steam at 100°C condenses on a 2-m × 2-m plate that is tilted 40° from the vertical. The plate is maintained at 80°C by cooling it from the other side. Determine
(a) The average heat transfer coefficient over the entire plate

(b) The rate at which the condensate drips off the plate at the bottom. Assume wavy-laminar flow. Is this a good assumption?
