Question

36. Carnot engine is operating between two heat reservoirs of 400K and 300K.
If the engine receives 4000J of heat energy from the reservoirs at 400K in each
cycle. How much mechanical work does the engine perform during each cycle?​

Answer 1

Explanation:

mechanical work = Kienetic energy + potiental energy

Kienetic energy =

$\frac{1}{2} mv^{2}$

potiental energy =

$mgh$
