Question

An ice chest is constructed of a 0.4 mm thick plain-carbon steel
plate, a 1.9 cm thick layer of Styrofoam {*k*=0.033 W/(m-C)}
and a 0.65 cm thick fiber glass liner. The cooler has inside
dimensions of 25x40x100 cm. The outside of the chest is exposed to
air at 25 ?C with *h* = 10 W/(m^{2}C). If the chest
is completely filled with ice, calculate the time for the ice to
completely melt. The heat of fusion for water is 330 kJ/kg

Answer #1

An ice chest is constructed of Styrofoam (k =0.033 W/m・◦C) with
inside dimensions of 27 cm x 42 cm x 105 cm. The wall thickness is
5.2 cm. The outside of the chest is exposed to air at 26 ◦C with
convective heat transfer coefficient, h =10 W/m2・◦C. If the chest
is completely filled with ice, estimate the time required for the
ice to completely melt. Write the assumptions used in the
calculation of time. The enthalpy of fusion for...
