Calculation of inlet pressure of the pump

AI Thread Summary
To calculate the inlet pressure of a piston pump operating at 400 bar, it's essential to consider the pump's design and the diameters of the inlet and outlet ports. The inlet port has a diameter of 7mm, while the outlet port is 2.8mm, which affects the flow dynamics and pressure calculations. The vacuum pressure at the inlet will depend on the force exerted by the piston and the specific characteristics of the grease being pumped. For accurate calculations, consulting resources specific to fluid dynamics and pump engineering is recommended. Engaging in a more specialized forum may yield better insights and solutions.

hello guys,
i wanted to calculate inlet pressure of the pump( vacuum pressure). pump operates at 400 bar.
pump works by sucking the grease from the inlet port of dia 7mm and delivers it through outlet port of dia 2.8mm. pump used here is piston pump. the force acting on the piston is 400bar.

regards
Ashwin

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
