In performing 100.0 J of work, an engine rejects 50.0 J of heat. What is the efficiency of the engine?
It is found that an engine rejects 100 J while absorbing 125 J each cycle of operation.
What is the efficiency of the engine?
How much work does it perform per cycle?
An engine operating between heat reservoirs at and extracts J per cycle from the hot reservoir.
What is the maximum possible work that engine can do per cycle?
For this maximum work, how much heat is exhausted to the cold reservoir per cycle?
A heat engine operates between two temperatures such that the working substance of the engine absorbs 5000 J of heat from the high-temperature bath and rejects 3000 J to the low-temperature bath. The rest of the energy is converted into mechanical energy of the turbine.
Find the amount of work produced by the engine.
Find the efficiency of the engine.
The Kelvin temperature of the hot reservoir of an engine is twice that of the cold reservoir, and work done by the engine per cycle is 50 J.
Calculate the efficiency of the engine.
Calculate the heat absorbed per cycle.
Calculate the heat rejected per cycle.
