SIZING A NETWORK
Select the Transair
®
diameter for your application, based on required flow against pressure drop.
Estimated values for a closed loop network, a pressure of 4 bar with less than 10% pressure drop.
Velocity: 4 m/s.

Equivalent Length
* These results should be taken into account in order to ensure the best practice for industrial water networks.
An anti-water hammer device is necessary for the protection of regulation components of other fragile elements.
I Example (with the above values)
• Main network length (main ring): 50 metres
• Required flow rate: 15 m
3
/h
• Working pressure: 4 bar
• Pressure drop< 10 %
• Velocity: 4m/s
• The most suitable Transair
®
diameter is: Ø60.
I DIN 1988
The pressure drop per diameter is stated for a flow rate and a velociy, at a temperature of 20°C.
