Hot Pipeline Local Pressure

Calculate high temperature pipeline local stationary pressure from elevation.

Elevation is measured relative to any arbitrary datum (+ve above the datum -ve below the datum). The external pressure is calculated from the water depth. The internal fluid density is assumed constant. The fluid is assumed statioanry (frictin losses are ignored). Use the Result Plot option to plot pressure versus elevation.
