Hi
I need to do calculations regarding sizing of min. flow line with RO for a pump. Appreciate if anyone can guide me & check my calculations are right or not?
Attached please find data for installation of min. flow line of pump with RO.
Following steps were followed.
· Pump Data Sheet is provided for refrence. Please note that fluid is TMA (Trimethyl Amine)
· 1st I did the line sizing, based on velocity through the pipe. i.e. 1-3 m/s. 4 inch dia pipe was selected based on it as shown

· As existing discharge piping is of 40 SCH so I selected inner dia of pipe of 102.3 mm for a pipe of 4” 40 SCH (kindly see if this selection is right because I am confused regarding it)
· Orifice dia was calculated through spreadsheet with a flow of 55 Nm3/hr (more than min. flow to counter friction losses due to piping & bends).
Kindly guide for liquid, Nm3/hr to be used or m3/hr. I think for liquid, it remains the same.
I found this spreadsheet on internet (i don't know exact location, my apology) and calculated RO dia

· Requested to kindly check it at your end from another sheet if this spread sheet has calculated it rightly, if possible
