Procedure PipeFlow in EES does not return any output results

[andradesilva]

Hi!


I started used EES (Engineering Equation Solver) very recently, to calculate pressure drop on pipes.
For that, I call the procedure PipeFlow. However, I do not get any output results. The output variables are empty and calculation time is 0 s. So I guess it does not calculate anything.

My code is:

Procedure pipeflow( Fluid$, T, P, m_dot, D, L,RelRough: h_T, h_H, DELTAP, Nusselt_T, f, Re)

Fluid$='Water'
T=70 [C]
P=1E5 [Pa]
m_dot=0.5 [kg/s]
D=0.03 [m]
L=0.1 [m]
RelRough=0.049

End



So the outputs here are: h_T, h_H, DELTAP, Nusselt_T, f, Re

How can I get the values for these outputs?

Thanks in advance,
Best regards
