Problem 7-58
A heated plate, 20 by 20 cm, is inclined at an angle of 60o with the horizontal and placed in water. Approximately constant-heat-flux conditions prevail with a mean plate temperature of 40oC and the heated surface facing downward. The water temperature is 20oC. Calculate the heat lost by the plate.
