Homework Statement
given the following diagram : http://www.freeimagehosting.net/uploads/…
a)mention for every step if it is isothermal / adiabatic / else. does
the system receive heat or emit heat.
b)given this gas is ideal gas, sketch a diagram with respect to P and V
c)calculate work done by 1 cycle, also calculate heat received by the
machine and its efficiency, compare results to carnot engine between
500k and 300k temp diff.
Homework Equations
S/R = ds/R = dQ/RT
ideal gas eq. pv=Rt (n = cons. here)
The Attempt at a Solution
i did part a and found that the process is isothermal->adiabatic->isothermal->adiab…
i cannot decide though where is the expansion and where is compression so I am having hard time decide about and p and v relations.
i would be very happy for assistance
