Given: 55 galloin water heater Height = 61 in. Dia = 21.5 in. Surrounding insulation : k=0.03 Btu/ft-hr deg. F Tank is in unheated Basement@ 60 deg.F Heat transfer coeeficients of inner and outer surfaces are: 65 and 14 Btu/ft^2 hr Deg.F Thermal resistances negligible Find: Considering only loss of heat from water heater, what is total energy loss for 6 months continuous operation (do not include energy to heat water initially or to heat water as is used) what is the required suface heat flux and surface temp. at exit.
