Homework Statement
Calculate thermal efficiency for a diesel cycle, given the following.
P_1, P_2, P_3, P_4, V_1, V_2, V_3, V_4,
T_1, Specific Gas Constant, Specific Heat Capacity at constant pressure.
Homework Equations
Unsure, can't find notation for specific gas constant and specific heat capacity.
Thermal efficiency i think is heat in divided by heat out?
The Attempt at a Solution
I think to start i need to calculate T_2, T_3 and t_4. However i am unsure how and why i need to use the specific gas constant and the specific heat capacity?
I have calculate the work done for the pressure and volume points.
I have done loads of reading on this and managed to solve 90% of the problem, this is my final stage, however, i am not at a loss and have so many equations floating around my head i am dreaming of them.
Needed a.s.a.p to finish project.
Thanks for any help
