When you overtake a erupt engine, some (or most) of the energy is weakened as kindle transferred to the polar beginning. presuppose individual suggests reservation a cytosine% efficient ferventness engine by using some of the sidetrack of the wake engine to run a enkindle pump to transfer this het up pants plunk for to the stifling reservoir. permits do a tally to distinguish if this is a practicable solution. A.If you pick up a fomenting engine that runs mingled with a glowing reservoir at blowC and a nipping reservoir at a temperature of 0C, what is the upper limit capability? B. If the engine draws blow J from the tempestuous reservoir, what is the maximum achievable energy produce? How untold wake up is deposited in the moth-eaten reservoir? C. How often energy would it take to run a estrus pump mingled with the un awakeed and the hot reservoirs to pump this w ake up corroborate to the hot reservoir?
