A furnace can supply heat steadily at a 1327 degree C at a rate of 800 kJ/s. The maximum amount of power (in the unit of kW) that can be produced by using the heat supplied by this furnace in an environment at 27 degree C is:

Solution

Q_in=800 \"kJ/s\"

TL=300 \"K\"

TH=1600 \"K\"

W_max=Q_in*(1-TL/TH) \"kW\"

=800*(1-(300/1600))

=650 KW
