Unformatted text preview: c v and c p : Under isentropic assumption, from Eq. 6.20a, we can calculate s o ( T 2 ) : 4 Utilize the ideal gas law in addition to s 1 = s 2 , to derive relationship for v 2 / v 1 for air going through an isentropic process: 5 Ideal gas going through isentropic process with constant c v and c p : Then from Equations 6.22b and 6.21 b one gets, respectively: 6 Polytropic Process: P v n = constant Constant Pressure Heat addition at constant volume Diesel engines Constant pressure heat addition Gas turbines 7 Example 6.9 Use A22E: pr2 = 21.18, pr1 = 1.3860 p2 = 15.281 atm From Table A20 E K at 850 o R (390 o F) is 1.39 p2 = 15.26 atm....
