## 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 dont know how to solve for P1 or P2 just stuck here
