1.) A Carnot engine is coupled to a Carnot refrigerator so that all the work produced by the engine is used by the refrigerator in extraction of heat from a heat reservoir at 270K at the rate of 4 kJ/s. The source of energy for the Carnot engine is a heat reservoir at 500K. If both devise discard heat to the surrounding at 300K, a. How much heat does the engine absorb from the 500K reservoir? b. If the actual efficiency of the engine is n= Ncarnot /1.5 and the COP = COPCarnot/1.5, how much heat does the engine absorb from the 5O0K reservoir?

A reversible engine converts one-sixth of heat input into work. When temperature of sink is reduced by 70 degree Celsius, its efficiency is doubled. Fin temperature of source and sink.
I have been working on this problem for a while and keep getting wrong answers with many different meathods how do I solve for Q0 here?
The capacity of a refrigerator is 200 TR when working between -4°C and 220C. Determine the mass of ice produced per day from water at 22°C. Also, find the power required to drive the unit. Assume that the cycle operates on reversed Carnot cycle and latent heat of ice is 336 Krkg.
I need a step by step solution please :)
(b) An irreversible heat pump with COP of 2.4 is used to heat water to 80°C for cleaning purposes. This heat pump absorbs heat from surrounding at 30°C and received the entire power, W from a Carnot heat engine operating between 250°C and 30°C. The Carnot heat engine received 6.3 kW of heat from the high temperature source. i) Draw the schematic diagram of the above system. ii) Determine the power received by the heat pump, W from Carnot heat engine, kW. iii) Calculate the rate of heat supplied to the water by the heat pump, kW. iv) Determine the COP of the heat pump if it operates on a reversed Carnot cycle.
