Pipe Sizer - Pressure/Gravity vs Fan Law Calculator Usage & Stats
Pipe sizing app for water systems - both pressure and gravity. Supports S.I and I-P units.
The calculations are based on the Hazen-Williams equation for the pressure systems and the Manning's equation for the gravity systems.
User can pick from a variety of currently available pipe materials, more will be added in future updates based on users requests.
The app automatically recommends the most suitable pipe size for the required flow rate, based on friction rate and velocity limits set by the user.
Any feedback is welcome, and will be the basis for subsequent updates.

The Fan Law Calculator App has been designed to allow quick estimation of the performance impact of variation in airflow and/or rpm on an existing system. The standard fan law equations are used to estimate the system performance changes.
Input the current values for airflow, rpm, pressure and current (or power) into the appropriate text field. The calculations will automatically update as you type.
The updated values can be input in one of two ways. The new values can be entered into the appropriate text field. Or, you can drag the airflow value left and right on the graph view to change the values. The calculations will automatically update as you edit the values.
Calculations
The standard fan law equations are applied:
cfm2 = cfm1 * rpm2/rpm1
sp2 = sp1 * (cfm2/cfm1)^2
power2 = power1 * (cfm2/cfm1)^3
Notes:
This application (App) is provided for use by qualified HVAC engineers and designers in the design of air handling systems and is not a substitute for appropriate design services. When in doubt, contact a design
