Homework Statement
Find the maximum temperature in deg C of the dual cycle with initial temperature of 30 deg c, compression ratio of 6, cut off ratio of 2.5 and the heat addition at constant volume process of 600 kj/kg.
y= 1.4
cp= 1.005 kj/kgk
cv=0.718 kj/kgk
rv=6
rc=2.5
Qadded @ Cv = 600kj/kg
Homework Equations
isentropic compression (1-2)
T2/T1=(V1/V2)^y-1 or T2/T1=(rv)^y-1
The Attempt at a Solution
process (1-2) isentropic
T1= 303k
solving t2
T2=T1 (rv)^k-1
T2 = 620.4 K
I don't know how to solve for P1 or P2 just stuck here
