Pumps & Systems - February 2018 - Pumps & Systems October …

Efficiency is expressed in percentages on the right of the pump curve graph. The BEP is represented by the efficiency curve’s peak, with efficiency declining as the curve arcs away, either right or left, from the BEP. Knowing the efficiency percentage will also help calculate horsepower required for an application.

Slurry Pumps Basics ǀ What is a Slurry Pump ǀ Slurry Pumps ...

Efficiency, of ,Slurry Pumps,. ,The efficiency, of a Slurry Pump is the ratio of energy delivered by the pump and energy supplied to the pump shaft. Pump ,efficiency, varies based on total head (vertical axis) and the flow (horizontal axis). When selecting a pump its operating range should fall around its best ,efficiency, range.

ESP system selection and performance calculations - PetroWiki

19/1/2016, · The free gas equals the total gas minus the solution gas. The volume of, oil (Vo), at the pump, intake is equal to stock-tank barrels multiplied by Bo, the formation volume factor., The volume of gas, (Vg), at the pump intake is equal to the amount of free gas, multiplied, by Bg, the gas volume factor.
