Heat is transferred to a heat engine (runs on a thermodynamic cycle) from a furnace at a rate of 80 mw. if the rate of waste heat rejection to a nearby river is 50 mw, (a) identify the thermal reservoirs, (b) determine the net power output, and (c) the thermal efficiency for this heat engine.

37.5%

Explanation:

We define first our values, that are,

We can now calculate the net power output, that is

Thermal efficiency is given by

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

the inner core.

good luck: )
