A backup electric generator for a home is connected to a tank containing 95 gallons​ [gal] of liquid propane. Combustion of liquid propane releases 50 megajoules of heat energy per kilogram​ [MJ/kg] of propane. Liquid propane has a specific gravity of 0.493. During a 15​-day [d] power​ outage, all of the liquid propane in the tank will supply the total energy needed by the home. Determine the efficiency of the system expressed as a percentage​ [%]. Assume that the home uses an average of 21 amperes​ [A] of electricity at 120 volts​ [V].
