Thanks all for your answers. I forgot to mention that there is a blowdown valve (closed during normal operation) upstream the RO, so in no-flow condition the 150# pipe is not at 1400 psig. Thanks again, I really appreciate your comments. Regards.

Hi everybody, I'm a junior process engineer and I'm facing my first RO sizing and specification, it is a restriction orifice for gas blowdown from a pressure vessel. The blowdown is from 1400 psig to 30 psig in 15 minutes according to client's standards. The RO has a block valve downstream in...

The sample is to be taken through a thief hatch and the product is diesel. Thanks a lot.

Hi everybody, I am wondering if there is any information about sampling procedures of API tanks with N2 blanket, the sample is to be taken from the tank roof through the manhole and during normal operation. I know it might looks kinda weird but my chief is asking me to find information about it.

Hi everybody, I would like to know if somebody has any information regarding viscosity, specific heat and thermal conductivity of calcium nitrate/ammonium nitrate aqueous solutions (both solutes in water). I'm designing a helical coil to heat this solution (65% Ca(NO3)2, 6% NH4NO3, 29% Water...

Thanks a lot for your valuable comments...

Hi everybody, I have read about pipe wall thickness calculation using B31.3 and I have seen that the final wall thickness considers manufacturer's tolerance (For Example, 12.5% for A106). My question is ¿do I also have to consider this manufacturer's tolerance when I'm calculating under other...

Hi, I would like to know what is the best procedure to calculate pressure drop through a Tee with different diameters. The flow is entering by one end (Q1 12") and is being divided into the branch side (Q2 8") and the opposite end (Q3 12"). I'd like to know how should I calculate the pressure...
