Dear All,
I need to analyze surge case in my piping system. It is Pipeline system that use for distribute Solar Diesel, in this case ineed to analyze line from Pump to Filling Shelter that use for unloading Solar Diesel from Tank to Truck. The problem is that the PRV make a noise. Drawing can bee see at the attachment below.
The line is 6" in size, the pump 1s 100 m3/h, length from discharge to Bottom Loading arm at Filling shelter is 40 m. Discharge Pressure 5.31 bar, system design pressure 8 bar, system design temperature 48 C. Code ASME B31.4, with pipe material A53 Grade B.
I want to model from discharge nozzle to line at filling shelter (Bottom Loading Arm), the problem is i can't make it as one model because as you see at the drawing there is a Corrugated Metal Hose with sigle Braid after the line PRV in Discharge Line, as i have read before in this forum that we don't need to model this Metal hose or if we model it, just model it as half part and give restraint/support after it.
For information it is not causing by cavitation because the NPSHa is Above NPSHr, for vibration case there is a Single Braid MetalHose that take care the expansion and vibration.
so my question here is there a method that i can use to analyze this system or can you enlighten me please about how must i model this case in CAESAR II, so i cancheck water hammer case?
