# How to Use Pump Curve to Select a Pump for Your System

If you have the pump characteristic curves from your pump supplier and already managed to plot the system resistance curve for the piping system you are designing then it is really very easy to finalize the selection of pump. All you need to do is to find out the intersection points of the different pumpRead more about How to Use Pump Curve to Select a Pump for Your System[…]

# How to Create the System Resistance Curve for Open System

Refer the concept of the system resistance curve from my previous article for better understanding this article. You will find an important equation there: Total system resistance = Frictional resistance + Resistance due to static head (height difference)  + Resistance due to pressure head (pressure difference) + Resistance due to velocity (typically neglected)…………………Eq.1 The aboveRead more about How to Create the System Resistance Curve for Open System[…]

# 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 axis for fluid handling piping system as well as HVAC fan system.   For the fluidRead more about How to Create the System Resistance Curve for Closed System[…]

# 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. A typical pump curve graph or chart (say for a centrifugal pump) is shown below:  Read more about How to Read a Pump Curve[…]

# Water Pipe Sizing Calculation Example – Part 2: Determining the Effective Pipe Length

Refer the Part-1 of this piping system design calculations series to know the problem statement and the assumptions. What is Equivalent Pipe Length Method? This the way of converting the Tee bends, valves and other pipe fittings in terms of equivalent pipe length. This value is added to the already existing pipe length to calculateRead more about Water Pipe Sizing Calculation Example – Part 2: Determining the Effective Pipe Length[…]
