I have a pipe with 10 mm in Diameter and 2 bar pressure, the fluid velocity is 200 m/s, the fluid is air.
is there a way to reduce velocity without affecting the pressure value?
A flow rate in a pipe is driven by a pressure difference and depends on the viscosity of the flow. Your specific flow problem in the pipe is compressible, viscous, at constant area, you can use the Fanno theory to explain what happens.
In this theory you can see the viscous effects on the flow like a flow in a reducing diameter due to the BL.
the given parameters do not make sense. Is the pressure drop 2 bar & over what length of pipe ? Or is the entry pressure 2 bar, at what temperature is the air? answers will be very different for sub-sonic , sonic or supersonic velocities. The velocity given of 200 m/s seems very high what' this from? The allowable pressure drop over the given length of pipe also affects any possible answer to be given.
Alex Pathan the entry pressure is 2 bar the velocity of air is 500 m/s what I asked for is there any solution so I reduce the Velocity without afecting the pressure value?
