Hi everybody, my question is very simple, I think but I can't have a point on it:
in brayton cycle there's the isobar step, during the combustion process... everywhere I read that this step is isobar, but I am guessing how can it be isobar if temperature of the gas rises because of combustion...
Hi everybody, how does pressure varies in the vent pipe connected to a PSV? I think it should go from the opening pressure of the valve to 1 ATM or 100 KPa (atmospheric pressure). If I am right is this variation linear during the lenght of the pipe? Does it happen suddenly at the open side of...
Hi, I perform stress calculations using Coade Caesar II. I noticed that in sustained cases allowables undergo variations (they diminish) at the points with SIF (stress intensification factor). Though I can understand why I cannot find a B31.3 formula or paragraph that justifies this behaviour...
Hi, I have noticed that water lines in the oil plant I am surveying have valves and sometimes lines are made of various materials, above all bronze and cast iron, sometimes steel.
Could you explain how to choose one or another material and the criterions?
Lines are cooling water, raw water...
Hi everybody, I found that in most cases these kind of valves have an outlet with littler flange rating and bigger diameter than the inlet, I ask you why. Maybe the rating is for the pressure reduction but I really can't explain the bigger diameter.
Many thanks
If a fluid changes diameter passing through a reducer, let's say from 10" to 8" what happens in terms or pressure?
Excuse me for the silly question but in the office someone made doubts arise.
As I wrote in the subject I would like to know what's the function of reducers in a by-pass, I attach a little picture to clarify things, I hope you will answer me, many thanks.
Hi everybody, I am new to this forum as a registered user and this is my first question, I sure I will get good answers. Excuse me if my English is not perfect.
I work for a laser scanning survey company, I am however new to this work and I ask those who have experience in this field or if some...
