A carnot engine has 40 gram of helium gas as its working, Ask an Expert

Academics

A Carnot engine has 40 gram of Helium gas as its working substance. It operates between two reservoirs of temperatures T1= 400 Celsius and T2= 60 Celsius. The initial volume of the gas is V1= 2e^-2 m³ and the volume after isothermal expansion is V2= 4e^-2 m³ and the volume after the subsequent adiabatic expansion is V3=5e^-2 m³.

a) Compute the work generated by this engine during one cycle.

b) Find the heat absorbed and the waste heat ejected during one cycle.
