Hi, I'm trying to plot this for different T3 variables ( 900,1100,1300,1500,1700) in same graphs and each line should be different colour or type.

I attached the graph that ı want to plot. Please help, thank u in advance

clear;
T1=15+273;
for T3=900:200:1700
etatis=0.88;
etacis=0.88;
etayan=0.98;
etamek=0.95;
cpb=1.115;
cph=1.005;
cpg=1.147;
P1=1;
Hu=47966;
epsilony=0.02;
epsilonk=0.03;
epsilonc=0.01;
kh=1.4;
kg=1.333;
for Prc= 0:0.5:50
a=(kh-1)/kh;
b=(kg-1)/kg;
Prt=Prc*((1-epsilonk-epsilony)/(1+epsilonc));
T4=T3*(1-(etatis*(1-(1/(Prt.^0.2498)))));
T2=T1*(1+(((Prc.^0.2857)-1)/etacis));
wut=cpg*(T3-T4);
qy=(cpb*(T3-T2))/etayan;
wk=cph*(T2-T1);
wnet=wut-(wk/etamek);
etatermik=(wnet/qy);
plot(Prc,wnet,"b.-")
xlabel ('Prc', 'fontsize', [14]);
ylabel ('wnet ', 'fontsize', [14]);
grid on 
hold on
end
end
