    Pressure drop across a control valve

    Hi all, Thanks for the responses. I am glad the question was not as simple as i thought it would be....anywyas.....continuing the discussion further...i had two more thoughts- 1. For sizing a valve...the Cv is determined for a constant pressure drop across a valve? 2. for a good orifice...

Let me make things little simpler......as i understood in school that we can have two types of control valves....pressure control valves and flow control valves. My question is with regard to the 2nd option of a...

    outlet composition from HCL tank

    Hi, You need to tell if the HCL is gas or an auqeous solution. If its just HCl gas, let us know the air flowrate. Can then help you know the composition ofHcl in the air outelt stream.
