Reference Book:Introduction to Chemical Engineering Thermodynamic 7th Edition by J.M Smith ,H.C. Van Ness

An ideal gas is changed from P1 = 1 bar and V1=12 cubic meter to P2=12 bar and V2=1cbic meter

by the following mechanically reversible processes:

(a) isothermal compression.

(b) adiabatic compression followed by cooling at constant pressure.

(c) adiabatic compression followed by cooling at constant volume.

(d) heating at constant volume followed by cooling at constant pressure.

(e) cooling at constant pressure followed by heating at constant volume.

Calculate Q, W, ?Ut, and ?Ht for each of these processes and sketch the paths of all

processes on a single PV diagram.

Notes:

Explanation / Answer

(e) cooling at constant pressure followed by heating at constant volume.
