I will set the equation like this: right?
How to put values on the below equation? What is K value? (I don't know how to transfer to head form) Is it size of pipe and viscosity relating to kinetic energy head so that K x v2/2g?
Thank you for your help:)
1. It is water
2. take 20oC temp. Dynamic viscosity of water (in mPa.s) is 1.
3. 10meters for 50mm dia. iron pipe(take same pipe roughness) ; 10m for 20mm dia. iron pipe ; 10m for 30mm dia. iron pipe. they averagely branching to same elbow and not other fitting or valves.
4. assume the water...
For above pipe or duct flowing (where point A and C are higher diameter than B), same volume flow for point A,B & C.
Velocity B > Velocity A & C ; Pressure energy A > Pressure energy B ; friction pressure B > friction pressure A.
Question one: When pipe or duct sizing to be reducing even...
Thank you all so much! Really appreciated. I was thinking some analogy between electrical and mechanical equation so trying to make the simplest and deepest unit or element for them by analogy mindset. It seems not correct to deepest.
I am new here and I am seeking for help:) Thank you so much.
In engineering, electrical formula often analogy to mechanical formula.
eg. power[W] = pressure x volume flow rate vs power[W] = voltage x current
My question is could we make the simplest unit between electrical and mechanical...
