This predicts how much pressure would be needed to push the water along a pipe at a particular speed The formula looks like this: Here, the pressure difference P needed to achieve a flow velocity v depends on the length L and diameter D of the pipe as well as the density of the fluid (ρ - about 1,000 kg/m 3 for cold water)...

BACK TO BASICS: CHECK VALVE A lift check valve has a guided disc that is raised from the seat by upward flow pressure There are many different check valve designs, with the oldest and most common being the swing check Shown here is an example of an in-line check valveThis valve is also known as a nozzle check or silent check valve...
Ideal Lift of a Spinning Ball
Jul 28, 2008· Because of the change to the velocity field, the pressure field is also altered around the ball The magnitude of the force can be computed by integrating the surface pressure times the area around the ball , Adding up (integrating) the lift of all of the cylinders along the axis gives the ideal lift of the ball...

Ball mill
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc as well as for ore dressing of both ferrous and non-ferrous metals The ball mill can grind various ores and other materials either wet or dry...
Ideal Lift of a Spinning Ball
Jul 28, 2008· All that is necessary to create lift is to turn a flow of air The airfoil of a wing turns a flow, and so does a rotating cylinder A spinning ball also turns a flow and generates an aerodynamic lift force The details of how a spinning ball creates lift are fairly complex Next to any surface, the molecules of the air stick to the surface, as discussed in the properties of air slide...

classical mechanics
Yes, you absolutely need to count the back pressure Otherwise the force required would be essentially independent of flow rate or the properties of the flu For a given fluid, you need to assess the pressure needed inside the syringe to make the desired flow The force on the plunger needs to overcome that...
