    tank's drain size

    Hi,there: I am wondering that is there any general guide on how to decide a low pressure tank's drain size based on the tank's design data, such as height, diameter and capacity? Thanks.

    PSV for a piping line

    Thanks for you guys response. One pump is protected by a PRV and the other doesn't. What I am assigned to do is to protect, using a PRV, the pipe line after two chemicals mixed from liquid thermal expansion, I am thinking to use the total flow rate of mixed chemicals and pressure to size the...

    PSV for a piping line

    Hi, everyone: I need to size a PSV for a piping line which has two pumps working in Parallel, two different chemicals transferred by pumps and mixed in the protected pipe. The pumps have different operation parameters. I am going to do Liquid thermal expansion calculation for the protected...

    question about Fisher s200 Regulator

    Latexman: Thanks for your response. Actually I have that document on file. But with set pressure and port size I couldn't decide Cv and Cg for the valve we are using. You could decide Cv and Cg with orifice size and set pressure according to a table in the document. So what I am wondering is...

    question about Fisher s200 Regulator

    Hi, everyone: what are the port size and the orifice size for Fisher regulator? I am trying to decide Cv and Cg for an on-site regulator, what I have are Fisher S200, body size, port size and set pressure, how can I make a choice? Thanks a lot.

    control vavle flow rate calculation

    thanks for you guys help.I appreciate it. JimCasey: the inlet is at 53.2 pisa,280F and outlet is at 29.4psia 240F. inlet fluid is liquid(water)only. Could you help me to run it at flowserve? what are the equations for this case? Thanks lot!

    control vavle flow rate calculation

    TD2k: yeah, Q is in gpm. Cv is assumed normal Cv. I think it's Is this a single phase non-cavitating liquid.

    control vavle flow rate calculation

    I am calculating the flow rate through a control valve: steam condensate,liquid, temperature difference between inlet and outlet is about 40 F. Cv=127 Sg=0.924 Delta P=23.8 The equation I am using:Q=Cv*Sqrt(DeltaP/Sg),I got some number real big. I am wondering: am I using the right equation...

    Questions about the fire scenario for Condensate Flash Drum

    I need to size a PSV for a Condensate Flash Drum. I have some questions: 1)If the fluid is water, do I need to consider a fire scenario for relief valve and how? 2)In the equipment data sheet, the flash drum is shown as:"Insulation: Steel-banded". What does it really mean? Is it fire proof or...

    What's #/hr? every know?

    hi, there: Does anyone know #/hr, a flowrate unit, used to express max flow rate through a control valve? is it as the same as lb/hr? Many thanks.
