Asteam engine (assume a carnot engine ) has an efficiency of 50.8%. if the waste heat has a temperature of 72.4 ◦c, what is the temperature of the boiler? answer in units of ◦c.

The temperature of the boiler is approximately 147.1 °C

Explanation:

A Carnot engine is an ideal engine that has the highest efficiency among all the engines because the second law of thermodynamics.That efficiency  is:

with the temperature of the hot reservoir (the boiler temperature) and the temperature of the cold reservoir (the steam temperature). Solving for :

it should be all of them because it asks if you included all of those in your answer

explanation:

58750.08068 is the answer i think
