Two carnot engines a and b operate in series
WebA Carnot cycle is an ideal thermodynamic cycle proposed by French physicist Sadi Carnot in 1824 and expanded upon by others in the 1830s and 1840s. By Carnot's theorem, it provides an upper limit on the efficiency of any classical thermodynamic engine during the conversion of heat into work, or conversely, the efficiency of a refrigeration system in … WebMar 24, 2024 · Two carnot engines a and b are operated in series. The first one a receives heat at t1 = 600k and rejects to a reservoir at temperature t2. The second engine b receives heat rejected by the first engine and in turn, rejects to a heat reservoir at t3 = 400k. Calculate the temperature t2 if the work outputs of the two engines are equal

Did you know?
WebTwo Carnot engines A and B operate in series such that engine A absorbs heat at T1 and rejects heat to a sink at temperature T. Engine B absors half of the heat rejected by engine A and rejects heat to the sink at T3. When workdone in both the cases is equal, the value of T is : No worries! We‘ve got your back.

WebCarnot engine works on Carnot cycle. It consists of an alternate series of two reversible isothermal and two reversible adiabatic processes. Since each process is reversible, the Carnot cycle as a whole is reversible. Carnot cycle (Figs 3.12 and 3.13) is independent of nature of working fluid. It can work with any working substance like gas ... WebTwo Carnot engines A and B are connected in series between two thermal reservoirs maintained at 1000 K and 100 K respectively. Engine A receives 1680 kJ of heat from the high-temperature reservoir and rejects heat to the Carnot engine B.Engine B takes in heat rejected by engine A and rejects heat to the low-temperature reservoir.
