pump discharge pressure

pump discharge pressure

(OP)
Hello All:
need your help..
I want to read the differential pressure across the pump accurately. see the attached sketch
There is a electric heater on the discharge of the pump
I have a suction gauge very close to the pump and the discharge gauge tap is located on the heater outlet roughly about 8 ft from the pump discharge flange. From the tap there is a 1/4" coiled tubing brought down and the gauge is located roughly on the same elevation as the discharge flange
Currently the discharge pressure is reading 125 psig
question: what is the actual discharge pressure. is it the same as the gauge is reading minus the heater pressure drop and minus the pressure drop from the pump up to the pressure tap. I say this, because the gauge is located down and liquid head is acting on it making it read the pressure at that elevation
Please comment
Kind regards,
Araza

RE: pump discharge pressure

Guage pressure plus heater pressure drop assuming that the coiled tubing is full of the pumped liquid. The change of elevation of the guage corrects for the tapping point being higher than the discharge nozzle.

Thanks..
Just so I'm perfectly clear. The heater pressure drop is 1 psig and the gauge is currently reading 125 psig
So the true discharge pressure near the pump discharge flange would be 125+1 = 126 psig
Thanks

That's what it looks like to me based on your sketch and info.
