Parker Transair 2019

116 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. Estimated Flow Rate 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 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 I DIN 1988 The pressure drop per diameter is stated for a flow rate and a velociy, at a temperature of 20°C.
