How can one find the characteristic system curve for a system with two different branches, each with its own fluid, T and centrifugal pump, that will than converge in a single line making a whole new fluid at a new T ? Thanks in advance ..read more

Hello,
I am trying to simulate the load-unload test in Abaqus under the following loading schedule using my UMAT (which has already been validated).
As you see, the load-unload test is pure tensile with positive displacements; however as I modelled it in Abaqus the...

Hello everyone,
I hope somebody can assist me with this. I am working on a calculation for a planet gear with 4 sun wheels and 1 planet wheel. The aim is to determine the forces on the sun wheel. Initially, I have 3 equations and 4 unknowns. By making an assumption based on symmetry, I now have...

The pump has an outlet size of 4 inch
1) In case 1, 4 inch pipe is connected at length of 20 m
2) In case 2, 2 inch pipe is connected using reducer
In both cases the pump outlet conditions are same( having same flow rate at a given pressure)
What happens to pressure at the end of the pipe in...

Thanks to anyone who can assist. (I have a curious mind but a limited grasp of the physics here.) Ocean waves hitting the shore carry a lot of kinetic energy. Let's say I capture this energy with a number of hydraulic cylinders and want to harness this energy by connecting it to a generator. The...

I had a stainless steel of Diameter 1000mm with a sheet thickness of 1mm. I have perforated that whole sheet through punching machine and there is 25mm margins (border) along the circumference. Now, that sheet is not flat now due to the expansion , I guess. I made a single cut equal to the...

hello
I am a simscape mulibody user
take a four bars mechanism, no external load
you apply a constant torque to the crank
I would expect a periodic angular acceleration but acceleration keeps growing
anybody here using simscape mechanics ?

Hello,
Looking for help with a physics problem.
I am dealing with a problem regarding the flow discharge between 2 open water bodies connected by a concrete sluice with gates. The issue is that the channel is not straight but rather a trapezoid (image of the cross-section below). The discharge...

Hi everyone,
I am in the process of designing a watertight enclosure for 300m deep applications and would like to explore options of using radial o-ring seals in place of face-seals due to space-savings. However, i am unable to find any information anywhere on using radial seals on non-circular...

Hi Everyone,
I'm trying to do a "Random Vibration Fatigue Analysis" on a bracket assembly that is mounted on the headboard of a pickup truck.
BACKGROUND:
The bracket assembly is mounted on the headboard of the truck using 2xbolts (1 per each mount). The truck regularly travels on a rough...
