Creating Energy Gradelines in Profile View
Use the Energy Gradeline command to draw the energy gradeline of the current
pipe run in profile view. The energy gradeline is a graphical representation of
the total energy of the flow through the system in terms of potential energy.
The vertical difference between the hydraulic gradeline and the energy
gradeline is the kinetic energy of the fluid per unit weight, V

/2g.
The values used by the Energy Gradeline command are calculated in the Pipes
Run Editor which you can modify to suit various needs.
