 heating element (L=0.6m and D=7mm) which has a surface temperature T=140C.

heating element (L=0.6m and D=7mm) which has a surface temperature T=140C. a) Make a simple 2-D sketch of the heater labelling the parts and state your assumptions Determine the saturated temperature (in C ). (do not interpolate, use the nearest value). b) Identify the correct boiling regime, and calculate the heat flux, (in W/m2 ) at the heated surface. c) Calculate the boiling heat transfer coefficient, (in W/m2K ). d) Calculate the electrical power consumed, W elec (in W). e) Calculate the rate of evaporation of water, m evap (in kg/S). heating element (L=0.6m and D=7mm) which has a surface temperature T=140C. a) Make a simple 2-D sketch of the heater labelling the parts and state your assumptions Determine the saturated temperature (in C ).
