Good explanation sir, good English accent just keep on. God bless you .

[@karkun1466]

Good explanation

[@pravinpr61]

Very good explanation. Thanks a lot. Please make a video of sensors selection for flow or level or pressure etc

[@damithgayashan9873]

Super

[@user-fb7pn4wo6w]

Thank you

[@batyrbairam9757]

Thank you bro!

Control valve sizing pathi sollunga bro?

[@pkarthickei]

good explaination

[@learninstrumentationengine268]

Thanks 👍

[@Harpreetsingh-lz9lv]

Any software to measure...?

[@mehulpatel9579]

👍🏻

[@vijiashok]

Hi friend please suggest Cv for pneumatic for 1/4 inch flow control valve will give how much flowrate

[@learninstrumentationengine268]

Pl mention differential pressure across the flow control valve, flow rate of medium and specific gravity of the medium. Then only, we can calculate correct Cv

[@akankshasharma9000]

why 60 farenheight is considered only ?

[@yogendraelapa5962]

What about steam

[@manojprabhakars2407]

Bro please upload more videos

[@learninstrumentationengine268]

Ok sure

[@nelsleons2931]

I need clarification, which is the higher pressure drop across the valve, 50% open or the 100% open.

[@learninstrumentationengine268]

We cannot generally comment unless, we have process parameters and control valve specifications. Then only, we can find the high DP at which stroke conditions

[@parthparmar2781]

Can you please explain why water is taken at 60 deg F ? i am not understanding why we are not taking at any other temperature?

[@learninstrumentationengine268]

vaporization of liquid, density etc are common in 60 deg F in a controlled laboratory. That's why this temperature is taken as reference to use globally.

[@ashishgautam9189]

Please sir make in hindi video 🙏

[@veerendrajindal3653]

Plz hindi language m bnaye ye video

[@learninstrumentationengine268]

Sure

[@MoMo-Desert]

@@learninstrumentationengine268 no not not need hindi.. English pleaase

[@ITISANSAR]

Control valve coefficient should be low or hight?

[@learninstrumentationengine268]

This value is not for high or low. As per the volumetric flow for an application, we need to design the rates Cv.

[@ITISANSAR]

@@learninstrumentationengine268 bhai maine mcq wise pucha tha, mujhe kahin bhi iska ans. Nhi mila abhi tak,

[@thomasmathew4469]

Excellent one, but pls try to maintain the Indian accent than the make up US accent.

[@user-vu2nv2os2b]

His English is better understood by all engineers from all nations of the world.

[@bharatgohil9600]

Pls sir Hindi language
