Looking at the differences between conventional and captive-air tanks.

Let’s take a closer look at cavitation-causing conditions to gain a working understanding of a property called net positive suction head.

The third is a series on pump selection and pump performance curves and charts.

"An understanding of pump performance curves is an important part of a pump installer’s storehouse of knowledge."

The pump selection process, how to read pump curves and charts, and how to select the right pump.

Last month, we talked about friction loss due to pressure drop, with a look at the factors that contribute to friction loss – flow velocity, pipe size, length of pipe,

"So far in this series, we have examined two of the three factors to be considered when determining the pressure requirements of a pump – household working pressure and lift pressure. The third factor is pressure drop due to friction loss/"

"In the last two articles, we discussed how to determine the capacity and pressure requirements of a typical residential pumped water system. This month, we will look at a multi-use system, one which might serve a farm."

"There are three factors that go into the determination of the pressure required from a pump in a residential water system."

Sizing a residential water system involves several considerations. Once you know the needed information, you can determine which type of pump best serves your application. Then, once you have determined which type of pump to use, you need to size the pump.
