Hi,
What is the effect of having a very high Total Differential Head. The reason for my question is:
NPSHA for the pump is 18 m
TDH is 18m
Is there any relationship with the two?
thanks for your responces.
Hi,
Is there any rule of thumb for the preliminary sizing of the recycle line for a pump? If yes, at what percentage of the pump discharge flow is required to flow through the line?
Responce is highly needed.
sshep,
thanks for your comment.
I have requested from the company the pump characteristic of the exiting pump to determine the discharge pressure of the pump.
if i may ask, from your statement "To me 'discharge static head' is the discharge pressure of the pump in meters of head", if i had...
Doug,
what i did was to use the vertical pipe routing from the pump discharge to determine the static discharge head.
The discharge pipe run vertically upward and it enters an elbow to run horizontally before it then turns downward to enter the pipeline.
I hope my suggestion is right.

Hi,
In determing the pump discharge static head discharging into a pipeline leaving the platform, am considering using the length of the vertical lift of line from pump discharge + TOS (Top of steel reference for the platform) to the centreline of the pump. The pump is a new one to replaced the...
