THE MODULES OF PIPENET

Tel.: +44 1223 441311Fax:+44 1223 441297

Transient Module Features

• Speedy and cost-effective means of transient (dynamic) network analysis

• Prediction of pressure surges• Modelling of control systems in flow networks• Calculation of hydraulic transient forces • Possibility of interfacing with pipe stress

analysis programs

Tel.: +44 1223 441311Fax:+44 1223 441297

Some Models Available• Pipes: Rigorous, simplified.• Pumps: Simple, turbo.• Valves: Operating, non-return, check, liquid

surge, regulator, fluid damped check, inertial check.

• Tanks: Accumulator, simple, surge.• Vacuum breaker, air release valve.• Caissons• Control Systems: Pressure and flow

sensors, PID controller, transfer function.

Tel.: +44 1223 441311Fax:+44 1223 441297

Highlights

• Multiple fittings can be inserted on a pipe• Library of fittings + user defined fittings• Valve operation by a choice of time functions

or automatic control loops• Hydraulic forces (total and dynamic) for the

analysis of water hammer etc.• Vapour cavitation modelling• Automatic calculation of wave speed• Tabular, graphical and animated output
