You are considering two heaters in your house which must provide 10kW of heating. You expect to run it for 100 days per year, 16 hours per day. The first heater is gas and has an effiency of 40% but gas costs .01 cents per kWhr (kilowatt - hour) The electric heater is 82% efficient but the cost of electricity is .03 cents per kWhr Which is the cheaper option?

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.
. a. A group of engineering students designs an electric heater with a power rating of 15 kW. If 10 kg of ice at 200 K is placed in the heater, how many minutes will it take to change ice to steam at 400 K. Assume 100% efficient.
2) The energy consumed by a shower for 30 days is 22kwh. It is known that the resistance of the showerhead is 20 ohms and that its nominal current is 15A. So, what is the time in minutes that the shower was turned on during this period?
You have decided now that quarantine is about over to take a trip to Hawaii. You decide to rent a small house that has floor to ceiling windows. It is small so it is one floor. The length and width of the windows are 9m x 14m. There are 4 of them. It is a constant 950F (350C) outside and you really like it 650F(180C) inside. You have an air conditioner that operates at 75 percent Carnot efficiency. The windows are 6cm thick and the rest of the house is well insulated. a) How much electrical energy do you use in a day? b) What is the cooling capacity each day?
Based on the mechanisms of thermal energy exchange what would happen if you exercised in a colder place where it's 5⁰C.
An electric home stove with 3 burners and microwave is used in preparing a meal asfollows. Burner 1: 20 minutes Burner 2: 40 minutes Burner 3: 15 minutes . Microwave: 30minutes. If each burner is rated at 1.2 kW and the oven at 1.8 kW, and electricity costs 1000(IQ =Iraqi Dinar) per k Wh, calculate the cost of electricity used in preparing the meal?
The heat loss from a chicken coop (chicken house) is K(Tnside - Totside) during the winter, where K is 1.5 kW/K. The chicken coop temperature can vary between 15 °C and 25 °C without harming egg production. A heat pump with a coefficient of performance of 40% of that of a reversible heat pump is used to heat the chicken coop. What are the minimum power requirements if the outside temperature is -5 °C? .
A heat pump is used to heat a house. When the outside air temperature is 266K and the inside is maintained at 293K, the heat loss from the house is 195 kW. a. What is the minimum electric power (kW) required to operate the heat pump? b. What is the rate of heat transfer to the heat pump? C. What is the COP for an ideal heat pump operating between these temperatures?
A heat pump with a motor of 2 kW is used to keep a chicken hatchery at 30°C. This latter loses energy at a rate of 0.5 kW per degree difference to the colder ambient. The heat pump has a COP that is 50% of a Carnot heat pump. a- Draw a sketch for the entire system showing all energy transfers. b- Illustrate a heat pump operating between two constant-temperature energy reservoirs showing all energy transfers. c- What is the minimum ambient temperature for which the heat pump is sufficient?
Moving to another question will save this response. Question 3 Estimate the size of heating equipment (in kW), that is needed for a new dormitories in America that is 5.3 m by 7.4 m by 3.8 m high. A Moving to another question will save this response.
An electric resistance heater is used to provide space heating at an efficiency level of 100%. The electricity is sold at $0.13 per kWh. Question: How much money is needed if 1137.8 MBH is demanded? Hint: 1 MBH equals 1,000 btuh
(b) After graduation, you decided to work overseas to experience living in a country with four seasons. Your neighbour, knowing that you are an engineer asked your help to install a heat pump system for his house. He wanted to always maintain the temperature in his house at 24°C during winter. In that area during winters, average outside temperature is -3°C. He also has an underground water well with average water temperature of 10°C during winter. You estimated that the heat losses from the house under the average outside temperature to be 75000 kJh. Investigate the most economical mean to power the heat pump (by calculating the minimum power required) if you can choose to extract heat from either: i. The outside air at average temperature of -3°c ii. The well water at 10°C State the reasoning for your calculations.
