NPSH 8 Months, 2 Weeks ago  
With these data how we can calculate the NPSH of pump? (pump is operating near the sea):
1- suction pressure 8.8 kg/cm2G
2- vapor pressure 9.8 kg/cm2A
3- specific gravity 0.674
4- flow rate 450m3/h
5- inlet size 2"
Thank you.

NPSH Required by the pump is specified by the manufacturer. NPSH Available to the pump is a function of the fluid properties, the supply pressure, and the friction losses in the suction piping. Your list of data does not include enough details to determine NPSHA.
