I would like to mention about pipe size at discharge side:
1)My discharge line upto 2nd pressure gauge is 2 inch nominal size. (as shown in figure 1 of provided document) all of my PG1, PG2, Flowmeter, valve on that line.
2) Then I connected hosepipe of 3 inch nominal size upto tank (as shown in...
To PUMPyour help.SONLY & CVG:
I have solved the problem. It was because of increaseing pipe diameter in discharge side. Initially there is 2" pipe after second PG there is 3" pipe dia. This is root cause of problem. Thank you for help.
To QUARK:
Black hose before meter is a priming point. I prime pump by closing discharge valve and move air from that hose.
To PUMPSONLY:
PG#2 was before flow meter
PG1 & PG2 are in PSI. by varying discharge gate valve from fully open to fully closed I got following readings. The flow meter dP...
Dear PUMPONLY,
I really appreciate your guidance. I have changed taping point for pressure gauge. As you stated, I require digital pressure gauge to measure minor losses. Am I right?
But 60 PSI pressure drop is too much. This might be majorly because of Turbine meter. Right?
Any more...
Thank you for ur reply.
To IONE: yes discharge goes to atmospheric tank. You are right I did not get anything in that condition. I was varing conditions.
To PUMPSONLY: They have not indicated Pressure gauge location in HI 1.6 standard. Can you please suggest how much distance should be between...
Hello everybody,
Centrifugal Pump performance test (ANSI / HI 1.6 standards)
Gate valve: full open; Water Flowrate: 260 GPM(+/-1); Discharge pressure before gate valve 60 PSI; Discharge pressure after gate valve 0 PSI. Why there is 60 psi pressure drop across the valve?
I have tried...
Hello Everybody,
I am associated with new pump manufacturer. For me, it is understood that hydrotesting is required to generate (centrifugal) Pump curve and NPSHR calculation. Will you please tell me which factors should be consider during hydrotesting of pump? like tests the pump with water at...
Hello Everybody,
What is technical Difference between API 610 and ANSI B73.1 Crude oil transfer pump? I understand API 610 pumps are more costly compare to ANSI B73.1 pump.
Can we add ANSI B73.1 in crude oil refinery system where other pumps are API610? Which factors should we consider for...
To mbeychok,
Thank you for your reply. I am looking for average crude oil velocity. In fact I am looking for particular xyz refinery example in operation. If you or anybody working with refinery, can share practical experience.
To 1gibson,
Thank you for your reply. I am looking for crude oil velocity instead of volumetric flow rate. In fact I am looking for particular xyz refinery example in operation. If you or anybody working with refinery, can share practical experience.

Hello Everybody,
I am working on project to calculate average time required for crude oil to transfer between initial unit operations such as crude oil storage tank, desalter, crude oil furnace and distillation tower. I know it is continuous process.
Will you please tell me how much (average)...
