# Pump New Circulating Pressure

In drilling operations, circulating pressure refers to the pressure exerted by the drilling fluid (commonly called “mud”) as it circulates through the wellbore. Circulating pressure is affected by various factors, including pump speed, mud properties, and friction losses.

When the pump speed is changed (increase or decrease), it directly impacts the circulating pressure. For the pump new circulating pressure formula, the exponent factor “2” is used as an approximation and to determine the exact factor, two pressure readings at different pump rates must be used to calculate this value.
