Chapter 5, Problem 5.53P

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.

3.0 A cold storage is to be maintained at -5°C while the surroundings are at 35°C. The heat leakage from the surroundings into the cold storage is estimated to be 30 kw. The actual C.O.P. of the refrigeration plant used is one third that of an ideal plant working between the same temperatures. Find the power required to drive the plant.

Two Carnot heat engines operate in series. The first heat engine absorbs heat of 100kW at 400°C while second heat engine rejects heat at 100°C. If the efficiencies of the heat engines are the same,a. Draw the schematic diagram of the systemb. Find the intermediate temperature in between the heat enginesc. Heat rejected for both heat engines

Consider a heat engine rate of heat production at 85 MW and at the same time reject heat to a sink at 40 MW. From the formula file which formula number is applicable to determine the power output and thermal efficiency of the engine.

3.0 A cold storage is to be maintained at -5°C while the surroundings are at 35°C. The heat leakage from the surroundings into the cold storage is estimated to be 28 kW. The actual C.O.P. of the refrigeration plant used is one fourth that of an ideal plant working between the same temperatures. Find the power required to drive the plant.

See attached image. Please show clear solutions.

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? .
