Quite elaborative and neatly explained Sir. These are some of the most important concepts which are asked in Process Engineering Job Interviews and you made them look so easy!

Sir NPSH required kaise leta hai manufacturer samjh nhi aya baaki puri video maine baar baar dekha yaad ho gya pura concept 👍

@chintanconcept 9 ай бұрын

Thanks !! NPSH r (Calculated by pump manufacturer) They continuously reducing the pressure of the resource tank and calculate NPSH, Once total dynamic head (H = hd -hs) reduces to 3%, That value to be considered as NPSH r

Bro the direction of impeller vanes are wrong ...in this case water will churn inside the casing ... centrifugal force act nahi karega...baki explanation were to the point 🙌👌

Very good explanation Sir. But i have a question, if put a pressure gauge on the suction side of the pump ( near the pump). Is it correct to say NPSHA is equal to pressure reading of the gauge minus vapor pressure of the liquid? Thank you again

@chintanconcept 10 ай бұрын

Yes that is NPSH, Exactly.

sir, pressure balance mai velocity head ka term kyu nhi aaya

@chintanconcept 4 ай бұрын

I really appreciate your question Velocity = flowrate/area Usually in static pressure head calculation & NPSH calculation we ignore the velocity head term which indirectly affects total energy(also constant flowrate) is there. Actually NPSH = (Ps-Pv)/p*g - V2/2g but doesn’t affect on total values.(hardly in 0.0…) Hope it is clear

Sir pressure=force/area then how will be pressure decreasing along with area.

@chintanconcept 5 ай бұрын

Hi It’s important to clarify that P= F/A represents how pressure is calculated, not how it changes within a fluid system. Here's how increasing pipe size can impact pressure within a fluid system: 1. Velocity: When you increase the size of a pipe while keeping the flow rate constant, the fluid velocity decreases. According to Bernoulli's principle, as the fluid velocity decreases, the pressure increases. So, in a larger pipe, the fluid exerts a higher pressure due to this reduction in velocity. 2. Volume: A larger pipe can hold more fluid volume, which might affect pressure if there are changes in flow rate or demand. However, the pressure exerted by the fluid itself is not directly related to the pipe size but rather to factors like fluid density, velocity, and external forces acting on the fluid.

That is stagnation pressure

what ??

@msamirul1 2 ай бұрын

You are confused between when to prssure increase or decrease w.r.t Area. As per bernaulli principles as area increase pressure will increase and vice versa
