I want to measure effect of pressure and temprature on Density so
-I want to calculate first the effect of pressure on density at fixed temprature (for example density values for pressure ranges from 100 to 1000 psia at 60 F)
  • Then I want to repeate the same but at other temprature
Example of code
A=100
P=100:1000
Pc=1076
Tc=400
T=100:1000 %
for i =1:length(100)
pr(i)=(P(i)/Pc) %function of pressure
tr= T/Tc % this parameter function on temp
p=(pr(i)+tr;
This code run correctly if T= one value
but i want to repeat the same but at Temprature range from 100:1000

Ran in:
A=100 ;
P=100:1000 ;
Pc=1076 ;
Tc=400 ;
T=100:1000 ;%
[P,T] = meshgrid(P,T) ;
pr = P/Pc ;
tr = T/Tc ;
p = pr+tr ;
surf(P,T,p)
