Comparison of 4 Different Flow Control Methods Of Pumps - EEP

There are several different methods to match the flow to the system requirements. The four most common flow control methods of pumps are throttling, bypassing, on-off control and variable speed drive (VSD) control. These are illustrated in Figure 1. Figure 1 – Illustrations of pump flow control methods. A – throttling, B – bypassing, C ...

Can I Pump my Irrigation Water from a River, Creek, or Pond?

The pump has to be mounted less than 8 feet above the water level (the closer the better.) You need a pad of some sort to put the pump on, but it is best if the pump can be easily moved, especially if the water level fluctuates in the creek or floods. There is also the possibility of using a submersible pump.

Pumping Tests :. Aquifer Testing 101

Common types of pumping tests that you may perform include the following:. Constant-rate tests maintain pumping at the control well at a constant rate. This is the most commonly used pumping test method for obtaining estimates of aquifer properties. Step-drawdown tests proceed through a sequence of constant-rate steps at the control well to determine well performance …

Water level variations in some boreholes and the determined transmissivity values varying between 1.85.10-6 and 3.5.10-4 m 2 /s (average of 2.47.10-5 m 2 /s), indicate a probable influence of pumping on the water level in the aquifer. Groundwater flows preferentially in a west-east direction and could generally discharge into the Bandama River.
