Following the Waterhammer in pipelines program a new item by the same author is available. The new program is called Pump Designer. Here is a few words from the author:

By means of this program you will have a aid to design a pump station for a simple pipeline system (1 line). You will can introduce the flow parameters, select the pipe type, select a suction and a discharge pipe and you will can also plot the system and pump curve for the selection of the pump size. The program calculates also the friction and local loss, the cavitation and the pump power.

You will can simulate with ease, for example, different flow rates, velocities, types of pipe materials, pipe diameters as well as also to plot your proposed pump curve.
