Very nice presentation to understand about control valve.thank u

[@rameshhariharan2623]

Great, learnt lot with simple understanding

[@peterwagdy9756]

are these methods valid for power hydraulics valves too?

[@noopurpancholi4497]

great video.. may I know which equation may I used for steam?
Hope u reply me back.
Thanks

[@nasreddine3712]

what do u mean by loss coefficient please?

[@technicalrajtr441]

Nice

[@minthurahtun]

Thank you for the lecture. What should be the unit of molecular weight of the gas in this calculation? Is it gram/mole?

Does expansion valve of refrigerator follow flashing curve?

[@arnoldyobakouakam1099]

Thank you very much for this video. however i still have a question.
How to obtain the operating volume flow using the standard volume flow when the medium is water vapour?

I would think the SG value for the 20Deg C case should be higher than that of 98DegC case looking at the density temperature chart

great

[@alirezaalizade2728]

Good

[@kprz2024]

Where can i find the reference for the equations used?

[@bediosoro7786]

Good is there a book where I can find all these equations?

I can't believe Seattle did not run the ball

[@vinodp1184]

good but how to find F l, liquid pres recovery factor

[@danielbest98]

17:09 take a look at the chart where it says Fl and go to 100%

[@user-sm2sr6jf4h]

he sead you can find it from vendor catalog
