    Flow through existing Pump

    Thanks for the continued input. Based on the differential pressure on the pump, the flow curve, and the knowledge of system pipe size as 1/2" and 3/8" I've come up with an estimate of the max flow rate as 5 GPM. This estimate is based mostly on the fact that a higher flow rate would require very...

    Flow through existing Pump

    Scalleke: I am interested in your suggestions. Another engineer in this department also suggested measuring the power consumption of the motor as a way to estimate flow. Along the lines of if we know the votlage and amperage we should be able to get the horespower ... but it hasn't been fully...

    Flow through existing Pump

    I have been tasked with upgrading an existing process heating loop to a higher temperature. The system currently uses a glycol/water mix (30% by weight) to heat a small (1 lb capacity) mix bowl. The customer wants to upgrade the process to achieve 200 deg bowl temps. I have proposed using an...
