// aim : To determine
// the new pressure of the gas
// Given values
P1 = 300;// original pressure,[kN/m^2]
T1 = 273+25;// original temperature,[K]
T2 = 273+180;// final temperature,[K]
// solution
// since gas compressing according to the law,P*V^1.4=constant
// so,for polytropic process,T1/T2=(P1/P2)^((n-1)/n),here n=1.4
// hence
P2 = P1*(T2/T1)^((1.4)/(1.4-1));// [kN/m^2]
mprintf('\n The new pressure of the gas is = %f kN/m^2\n',P2);
// End
