b)Now, we reduce the heating element temperature to be at 115°C where heat 100 kW.m-2. What is the heating element made of? [Important: the steps in details to support your

answer. Moreover, surface tension of water:58.9 × 10-3 N.m-1 and Pr1 = 2.55. [20 points] To boil water at atmospheric pressure, a horizontal heating element (cylindrical)with diameter of 10 mm and ɛ = 1 is used. Under steady state boiling conditions, what is the surface temperature of the heating element required to have power dissipation at maximum 1000 W m-1 when ts -tsat > 120.c
