I am having trouble with this question...It is from "applied thermodynamics for engineering technologists" by Eastop (Q5.2 if anyone has it).....(adsbygoogle = window.adsbygoogle || []).push({});

The Question:

Two reversible heat engines operate in series between a source at 527°C and a sink at 17°C. If the engines have equal efficiencies and the first rejects 400kJ to the second, calculate:

(i) the temp at which heat is supplied to the 2nd engine ALL DONE :-) =208.7°C

(ii) The heat taken from the source

(iii) The work done by each engine

I have done part (i) and I know it's right but I have no idea what equations to use for the next 2 parts because heat and work are dependant on each other so I dont understand how I can find one without the other....

Thankyou in advance

Dave :-)
