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.
We define first our values, that are,
We can now calculate the net power output, that is
Thermal efficiency is given by
number of electrons for neutral cl
graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
