Head loss due to obstruction in pipe

[@achalgorawade779]

A uniform circular tube of bore of radius ‘a’ has a coaxial cylindrical rod of radius ‘b’. Derive
the expression for the axial velocity profile, in steady laminar flow of an incompressible fluid
under a pressure gradient ??

Moody's diagram par bhi daloo video sir ji

[@MDAZAD-et3py]

Bahut acha padate hai sir aa aage tak jaenge

[@caddrahul]

Does any body know
1. How to find the cracking pressure of the valve.
2. how to find head loss curve of the valve.
3. Minimum Pressure required to open the Valves.
4. Minimum Velocity required for valve performance.
I have a 3d model of the dual plate check valve.
pls teach me how to find such parameters.
