A heat pump with the COP of 3.8 supplies heat at the rate of 289 kJ/min. If a bar heater was used and the electricity cost R2.50 per kWh peak and 200 cents off-peak , how much would be saved using the heat pump for 7 days if the off-peak hours are from 22:00 hr to 6:00 hr for every day of the week. Provide the answers to 2 decimal places and insert the unit in Rands after the answer.

Round everything to 4 decimal places. Since Lucas is an engineer familiar with thermodynamics. He decided to create his own heat engine at home to avoid paying for electricity. He created a small, makeshift heat engine for trial. The combustion of his fuel, diesel, reaches a temperature of 750°C, while waste heat is disposed to the atmosphere at 50°C.He, then connected a generator and a heat pump to the heat engine to check the amount of power being produced. Assume that the heat pump will be used to warm his room to 25°C, while the outside temperature is at 5°C. Lucas’ rooms loses 85,000 kJ/hr of heat. And, 25% of the heat engine’s power output goes to the heat pump. How much diesel (in kg) needs to be burned by the heat engine to maintain the temperature in Lucas’ room? Assume carnot heat engine and heat pump. If the natural gas has a heating value of 22,000 BTU/lb,
Fill in the Dianks. A 5 Hp Carnot engine operates between temperature limits of 300°C and 50°C. Find the rate of heat wasted by the engine in kW. Qu **Express final answer in TWO DECIMAL PLACES. Do not round off in between solution. Type only the "numerical value". No need to include the unit and percent sign.
