A Carnot engine uses a hot reservoir consisting of a large amount of boiling water and a cold reservoir consisting of a large tub of ice and water. When 5650 J of heat is put into the engine and the engine produces work, how many kilograms of ice in the tub are melted due to...

Consider a Carnot engine operating between temperatures T_h_ and T_c_, where T_c_ is above the ambient temperature T_o_. A second engine operates between the temperatures T_c_ and T_o_.
Calculate (in terms of temperatures) the overall efficiency of the two-stage engine operating this way, and...
Is there a formula used to solve engine problems? For example a carnot engine is operated between two heat reservoirs at temperatures of 500K and 300K. If the engine receives 200 cal from the reservoir at 500K in each cycle. How many calories does it reject to the reservior at 300K?

Problem :
Consider an engine in outer space which operates on the Carnot cycle. The only way in which heat can be transferred from the engine is by radiation. The rate at which heat is radiated is proportional to the fourth power of the absolute temperature and the area of the radiating...
This is just a common problem solving question, which I cannot make, I suspect because I'm bad at maths. Anyway, I want to see it done, hopefully to grasp it. I am doing physics, so, it's an exercise from one of my books.
18-11. Show that the efficiency e of a Carnot engine and the...
Hey everyone,
I was sick when we started this unit. I've been trying to catch up, and need to ask a couple of broad questions.
1) What is a Carnot engine? Or the Carnot cycle? What is it used for ? Why do we can about perfect conditions??
2) When people keep mentioning...
