Well Pump Head Pressure

A direct driven sprinkler system.

Well pump head pressure.

Where p pressure psi h head ft. Given the lower system head the intersection of the h q curve with the system head curve is out towards the right end of the h q curve at or near runout. Whether you re pumping water or a heavy caustic solution the head achieved will be the same. Considering the thermal regime in the study area calculations indicate a pressure loss of about 4 2 bar since a well head pressure whp of about 15 8 103 kpa during the oxidizer injection and of 3 6 bar taking into account the ucg operation at slightly sub hydrostatic pressure in the target coal seam which is expected to be in an acceptable range for the chosen liner diameters and well dimensions.

Conversely if the pump is located above the water to be pumped then the suction head is positive and the pump head will decrease. The average pressure in a domestic water system with a pressure tank used. This is because the pump must use energy to bring the water to the level of the pump. This is because the water entering the pump applies additional pressure at the suction.

In this study it was decided to apply inner liner diameters of about 8 9 cm 3 and. Total dynamic head tdh. The relationship between head and pressure can be characterized by the following formula. If the water level is higher than the pump then the suction head is negative and pump head will increase.

When a pump is started up with an open valve there is initially little system head pressure acting in opposition to the pump head capacity curve. The pressure at the discharge of the pump however will be higher for the heavier solution.
