Extracted text: 1. A Camot engine operating between 775 K and 305 K produces 54 kJ of work. Determine (a) Qa, (b) AS during heat rejection, and (c) e. 2. Ten ft³ of helium at 20 psia and 80 °F are compressed isentropically 1-2 to 80 psia. The helium is then expanded polytropically 2-3 with n = 14.35 to the initial temperature. An Isothermal 3-1 retums the helium to the initials state. Find T2, V2, P3Qa, Qr, W,AS(3-1) and pm
