hi there,
I need to run the file "Integration" I found in the web.
the input parameters are:
N: 54000
Pin: 100000
T: 303.3500
Vp: 0.0250
At: 0.0033
I just keep getting after I put all the necessary input.
I really can't find the solution.

PAR.Ac = (pi/4)*((PAR.D1t^2)-(PAR.D1h^2)); %Compressor area
There's no information for your PAR.D1t and PAR.D1h. I guess these are diameters. Consider adding these:
PAR.D1t = input ('Insert outer diameter (m) ' )
PAR.D1h = input ('Insert inner diameter (m) ')
