1. Homework Statement
given:
diesel cycle,
P1V1 P2V2 P3V3 P4V4 - all known
T1 = 20°c
specific heat capacity constant pressure = 1000j/kgk
specific gas constant = 287j/kgk
compression index = 1.4
2. Homework Equations
heres where i am stuck!
3. The Attempt at a Solution
Hi all, I am unsure where to go with this one. I am guessing that i need to work out T2.T3.T4, but can't find in any of my notes where any of the γ or R come into play or how to get T2T3T4?. i have already calculated the work done for each stage in a previous part of the question so i have that. Just not too sure on where to go from here to calculate the efficiency of the cycle?
