1. Find the condensation heat transfer coefficient for
saturated Freon-12 at 50 C on a horizontal tube, having a diameter of 3 cm and
maintained at 40 C.

2. Saturated steam at 1 atm is condensing on a horizontal
tube at a rate of 300 kg/h. The tube is 2 m long and is maintained at 60 C.
Find the tube diameter.
