Hi,
I am currently performing some pressure drop calculations from a water filtration unit to a Deaerator (operating at vacuum). The Deaerator supplies water injection pumps.
The pressure at the control valve is 4 barg. The fluid from the valve flows 20 meters upward till it reaches a shutdown valve installed close to the inlet nozzle on the top of the tower.
How do I account for the pressure for the portion of the line downstream from the control valve?
See attached sketch
Thanks
