Operating Pressures

Max: 332 PSI(g)

Normal: 323 PSI(g)

Min: 313 PSI(g)

Operating Temperature: 248°F (120°C)

Liquid and particulate Removal efficiency : minimum requirement of 8 micron at 99.95% efficiency

Maximum pressure drop : 2 psi.

The Pressure vessel is having a Internal diameter of 660 mm and Shell length of 2,730 mm. Could anyone suggest equations to calculate the pressure drop across this pressure vessel. The inlet and exit nozzle sizes are 10" ( DN 250) x Sch 80S.

We shall calculate the pressure drop at the entrance of the inlet nozzle, across the cyclone bundle and at the exit of the outlet nozzle. Apart from these is there any area where the pressure is getting dropped? Please advise if the composition of the Air will impact on the pressure drop.

IF we are getting higher pressure drop as per the actual operation across the vessel ( around 3 Psi), what could be the reasons leading to higher pressure drop than the designed values ?

Let me know if require any more details regarding this issue.
