How to Create the System Resistance Curve for Closed System

Like  pump curve, this is another very important curve for the system designers.

What is a System Resistance Curve?

• This is a graph plotted with flow rate along X axis and the total resistance to the flow along Y

How to Read a Pump Curve

What is Pump Characteristic Curve Graph?

As the name suggest it is the curve which define the performance characteristics of a pump.

Basically, the pump performance curve is plotted with flow rate along X-Axis and Pressure Head along Y-Axis.

Water Pipe Sizing Calculation Example – Part 1: Overview

This water piping system design calculation example will use the Darcy-Weisbach equation to calculate the pressure loss in a pipe and using that value it will check the appropriateness of the assumed pipe size.

Problem Definition

Calculate and Understand the Significance of Reynolds Number and Viscosity

Quite often you have to calculate Reynolds number while dealing with hydraulics and pneumatics. Know how to calculate and appreciate its values.

Understanding the following two points will be helpful before going to the actual calculation and formula:

1. Dynamic
