Water at 1500 kg/h and 10°C enters a 10-mmdiameter smooth tube whose wall temperature is maintained at 49°C. Calculate (a) the tube length necessary to heat the water to 40°C, and (b) the water outlet temperature if the tube length is doubled. Assume average water properties to be the same as in (a).
