question

Consider a vertical cylinder which has an outside diameter of 1.0 ft and is 2.0 ft long. Steam is condensing on the outer surface. The temperature of the outer surface is maintained at 85°F with cooling water inside the cylinder. Determine a) the overall heat transfer coefficient, b) the total rate of heat transfer, and c) the total rate of condensation. The saturation temperature is 105°F.
