Assuming the tube surface to have a uniform temperature corresponding to that of the phase change, determine the water outlet temperature and total heat transfer rate for a water flow rate of 0.3 kg/s and an inlet temperature of 60°C. If H=W= 0.25 m and L= 3 m, how long would it take to completely liquefy the paraffin, in hours, from an initial state for which all the paraffin is solid and at 27.4°C?

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.
