I did an analysis under minimum conditions. I gave 82 bar to the inlet and 36 bar to the outlet and opened the valve to 20%. Cv 11 and automatically calculated the flow rate as 2600 m3/h. When I gave 82 bar to the inlet and 10,000 sm3/h flow rate to the outlet, the Cv value I obtained was 36.5...
I have never analyzed under minimum conditions. normally maximum conditions:
37-36 bar and 100000 sm3/h flow
but when I define the inlet-outlet pressure in the program, it automatically calculates the flow rate and calculates 10000 sm3/h. for your information.
I have never taken the minimum as a basis until now because my aim is to see the rated Cv value. for this reason, either by giving the inlet-outlet and seeing the flow rate or by giving the inlet pressure-outlet flow rate and seeing how much pressure drop the cage provides. I was not sure which...
this is a continuation of my other work, you think right. but I'm not sure how to give the flow rate. this is the first time I'm hearing from you. what I can't understand is, from 37-36 bar pressure, should I get a maximum flow rate of 100,000 sm3/h to pass through? or should I get 36 bar...
at first I chose 10“ but due to the deadline we had a 12” valve ready. that's why I chose it. they want the speed especially low. then I thought I would lower the cv value with the cage design. that's why I asked about CFD in another topic.
I want the valve to provide the maximum flow rate by entering the specified inlet and outlet pressures. at worst I want it to be close to the maximum flow rate.
When I give it as volumetric inlet and pressure output, the inlet pressure starts to rise to very utopian values and it gets ridiculous. for this reason, I give pressure to the inlet and flow rate to the outlet, which is correct according to both formulas. my understanding; when I give inlet and...
