Any lead?
Thanks!
Guys!
Here's a question that's been bugging me. I'm using the ISA Study Guide to study for the CSE exam. They have a question concerning gas flow through a control valve. The upstream and downstream pressures are 65 and 15 psig, respectively, and the question is what would happen to the flow...
When looking at the effects of process changes on flow through a valve(ie how does flow change if upstream pressure drops?), can we assume CV is a constant? Also, would someone offer rule of thumb on:
1. effects of upstream pressure, valve opening size on liquid flow.
2. same as 1 but with...
Hi--
I'm studying for the CSE and would like to ask for some tips on good wiring practice. Any help in leading me to the right websites or general comments?
Thanks!
Hi--
I'm studying for the Control System Engineering License Exam. Can someone offer a rule of thumb of double acting valve actuator regarding fail safe options?
Also, do you know some websites that offer free download of some ISA, NFPA, and ASTM codes ?
Thanks!
