Astraight fin is made from an aluminum alloy (k = 160 w/m-k) and is 0.5 cm in diameter and 30 cm long. the temperature at the base of the fin is 75oc and it is exposed to flowing air at 20oc with h = 20 w/m2-k. that is the rate of heat transfer from this pin?

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
