Hello everyone
I have to calculate the required Cv for a blowdown valve.
The fluid is boiler feed water. I know the mass flow, pressure and temperature input and output, corresponding to saturated steam (eg 50 bar, 263 ° C).
What formula should I use? Liquid or dry saturated steam?
Thanks
Hello everyone.
for the design of some nozzle check valve I have the following conditions:
- Mass flow rate max
- Mass flow rate min
- Upstream pressure
- Density
It is required that those conditions the valve allowing all the mass flow rate and that the valve disc does not vibrate on the...
Hello everyone.
I fill the data sheet for a choke valve. I know the fluid (gas) and the pressures of inlet and outlet. I have to give CV values required and the mass flow rate.
For example:
p1 = 234 barg,
p2 = 1 barg,
temperature = 20 ° C,
Density @ T1, p1 = 202 kg/m3,
molecular weight =...
Hello at everyone,
I must to design a multiple orifice choke valve.
I have the following data at the maximum:
flow: 13500 MMSCFD
Inlet pressure: 1300 psig
Temperature: 200°F
Outlet pressure: 300 psig
Specific Gravity: 0,683
State of fluid: Vapor
How do I calculate the Cv request?
I tried in...
Hello,
How can I figure out the flow coefficient CV under certain conditions?
The fluid is a gas.
Data available are: mass flowrate, inlet pressure, pressure drop, inlet temperature, vapour molecular weight,
compressibility factor, viscosity at inlet temperature and specific heat ratio.
I...
