QI: At winter design conditions, a house is projected to lose heat at a rate of 65,000 Btu/h. The internal heat gain from people, lights, and appliances is estimated to be 6500 Btu/h. If this house is to be heated by electric resistance heaters, determine the required rated power of these heaters in kW to maintain the house at constant temperature.

Question 2. A household with electric resistance heating plans to switch from resistive heating to a ground source heat pump. Annual heat consumption of the house is 30 000 kWh. Investment cost of the heat pump is 21 000 €. Heat pumps COP is 4.0. How much are the annual savings compared to resistive heating after the change of the heating system (in kWh)? Average price of electricity is assumed to be 12 c/kWh. Round off your answer to one decimal digit and enter it without the unit.

If a house needs a minimum heat transfer rate of 75 kJ/h (i.e., 75 kJ of heat needs to be transferred into the house during one hour) to maintain a pleasant indoor temperature. If one wants to use a heat pump with a COP of 5.55 to fulfill this heat transfer rate, what is the corresponding electricity (in kWh) consumption to run such a heat pump for one hour?
A heat pump with a coefficient of performance of 3.5 provides energy at an average rate of 70000 kJ/h to maintain a building at 20 °C on a day when the outside temperature is -5 °C. If the electricity costs 8.5 cents per kWh. Assume heating is 24 hours a day. (1) Determine the actual operating cost in $/day. (2) Determine the minimum theoretical operating cost in $/day.
One of the greatest milestones in human civilization is the establishment of equivalence between heat and work by James Joule in 1840s. This set the stage for utilization of energy in fossil fuel to do work that leads to industrial revolution and the release of green-house gases. For sustainable growth with reduced damage to our environment and for the sake of future generation, the present generation need to do the followings: Use more renewable energy such as hydroelectricity, solar energy, wind energy, biodiesel, etc. (iii) Understand fluid dynamics better to design more efficient turbine, propeller etc. Re-organize our economy by introducing tax on the emission of carbon dioxide and carry out life-cycle analysis of energy utilization for products made.
