A thermodynamic system undergoes a process in which its internal energy decreases by 300J. At the same time 120J of work is done on the system. Find the heat lost by the system. If 250 J is added to a system as heat and the same amount of work is done by the system, what are ...
FromEq. 7.13it is clear that the turbine work output can be enhanced theoretically by keeping the gas temperature (T3) in the turbine high complemented with continuous heating of the gas as it expands through the turbine. Since continuous heating is not practical, reheat is done in steps or ...
However, I don't see how to eliminate Tc from this equation. (The fact that the process is isentropic enables the calculation of Pc given Pin, Tin, and Te, but I don't see how this can help eliminate Tc.) Any help would be appreciated, thanks in advance! Last edited: Jun 26, ...
This means that at zero pressure, a special process can be realized; a macroscopic change of volume achieved by isobaric heating/cooling without any work done by the system on its surroundings or by the surroundings on the system. A neologism is proposed for these dWp = 0 (and in general,...
