Hello,
I am doing deflection analysis of a pipe using GRE (Glass reinforced epoxy) pipe for which i ahve the following properties @ 21 Deg. C from material supplier
Hoop Tensile modulus = 23250 MPa
Poisson's ratio axial/hoop = 0.93
Axial Tensile Modulus = 10000 MPa
Poisson's ratio...
Hello,
Can somebody help me to find
1) The magnitude of force along discharge(nozzle)pipe axis due to back pressure (assuming the valve is closed in the pipeline).
Pump Details :
Discahrge Pipe ID : 35.00 inches
Operating Pressure : 300 Psi
Distance between valve & nozzle end is 150.00...
Hi,
I have requirement where i need to validate the key (square of 1.25") strength using FEA. This key is between shaft & coupling.
I did hand calculations for the key but client insists on FEA validation even though it is safe in hand calculations.
Can any one suggest me the...
What are the forces acts on the discharge head for vertical pump ?
The discharge head is not having flange instead it is coupled to piping system through dresser coupling.
I would like to know how to calculate the forces exerting on the discharge head due to fluid back pressure (at shut-off...
Hi,
I am doing reed frequency (natural frequency) analysis for discharge head (DH) with motor using FEA. DH looks like a hollow cylinder with 0.375" thk. placed between two circular plates (Top and bottom) in vertical position. Motor is resting the top face of the top plate. I used lumped mass...

How to do reed frequency of vertical pump with motor in FEA.
Do i need to consider the motor frequency also while calculating the system (vertical pump and motor) reed frequency ?
I have motor data like CG, static deflection and weight.
Please help

Hello Friends,
1. Can anybody tell me to what extent the ASME SEC VIII Div.II code stress limits can be used in designing pump solid shaft. My understanding is that ASME code has to be compared only when we design vessels which are shell structures. Am i correct ?
2. Is it correct to...
Hi,
I want to simulate the pump shaft,key and sleeve as an assembly to check for strength. The assembly is loaded with torsion and downthrust (axial load along the shaft axis)
I am defining contact between shaft & key, key & sleeve, etc.
My question is what boundary condition should i apply...
