house is to be maintained at 20°C when the outside air is at -25°C. It is determined that 1800 kJ is required each minute to accomplish this.If an electric heat pump is used to supply this energy, determine the minimum theoretical work input for one day of operation, in kJ/day. Evaluating electricity at 13 cents per kWh, determine the minimum theoretical cost to operate the heat pump, in $/day. ($1 = 100 cents)If a heat pump whose coefficient of performance is 3.0 provides the required heating, determine the operating cost, in $/day

Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.
