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?
