Write a computer program to calculate the heat addition per

Write a computer program to calculate the heat addition per unit mass, the net work per unit mass, the thermal efficiency, and the mean effective pressure of an air-standard Diesel cycle. Plot each of the above quantities as functions of the compression ratio for p_1 = 1 bar, T_1 = 300 K, and for maximum cycle temperatures of 1200, 1500, 1800, and 2100 K.

Solution

Matlab code

cp = 1
Ta = 300
Tb = 1200
Tc = 1500
Td = 1800

%Heat addition per unit mass
heatIn = cp*(Tc-Tb)
print(\'Head addition per unit mass\')
print(heatIn)
%net work
netWork = cp((Tc-Tb) - (Td-Ta))
print(\'Net work per unit mass\')
print(netWork)

% efficiency
efficiency = netWork/heatIn
print(\'Efficiency\')
print(efficiency)
