can someone help me with question Help A heat engine is operating on a Carnot cycle and has a thermal efficiency of 48.5 percent. The waste heat from this engine is rejected to a nearby lake at 60°F at a rate of 800 Btu/min. Source TH Carnot HE 800 Btu/ min Sink 60°F Determine the power output of the engine. (You must provide an answer before moving to the next part.) The power output of the engine is hp
Question #1 : A heat engine operates at a steady state between a source at 500 K and a sink at 200 K. Determine the maximum power output of the device if heat of 50,000 KJ/ min is supplied to the heat engine.

2. A heat engine operates between a source at 1250 K and a sink at 300 K and is supplied with heat at a rate of 800 kJ/min. (a) What is the maximum thermal efficiency this heat engine could have? (b) What power output can one expect from this heat engine? You need to provide more than a numerical answer here!
5. A certain heat engine operates between 1000 K and 500 K a) What is the maximum efficiency of the engine? (ANS: 0.5) b) Calculate the maximum work that can be done per kJ of heat supplied by the hot source. (ANS: 0.5 kJ) c) How much heat is discharged into the cold sink in a reversible process for each kJ supplied by the hot source? (ANS: 0.25)
Fall 2019 PChem 2. A certain heat engine operates between 590 °C and 170 °C. (a) What is the maximum efficiency of the engine? (b) How much heat is needed from the hot source for each 1.0 kJ of maximum work done? (c) For each 1.0 kJ of heat discharged into the cold sink, how much heat is supplied by the hot source?

2. Two reversible Carnot heat engines operate in series between a source at 427°C and a sink at 17°C. If the engines have equal efficiencies and the first rejects 400kJ to the second, calculate: (1)the temperature at which heat is supplied to the second engine; (2) the heat taken from the source; (3)the work done by each engine.
A reversible heat engine operates between a high temperature reservoir at Th and a low temperature reservoir at Tư. The work produced by the heat engine is used to drive a reversible refrigerator that operates between the same two reservoirs. Determine if the low temperature reservoir is being cooled or heated.
