Hello Everybady,
I have this situtation here. I have a liquid in a bowl rotating at a very high RPM creating a
a static pressure of 130-140 bars near the head. Now at the head of the bowl, I have a stationary centripetal pump attached which carries my liquid (driving force is the static pressure (or the rotational force) of liquid inside the bowl) through a pipe which leads to a vessel which is also pressurized.
I have some question which I am trying to find for the past one week but it just eats my brain when I try to find the solution for it.
The questions are,
1) How should I calculate the pressure at the entrance of the channel of my centripetal pump, and pressure also inside the channel.
2) the liquid is transferred to a vessel and the pressure inside the vessel ranges from atm pressure upto 10 bars.
3) to make sure my liquid from the rotating bowl reaches the receiving vessel, I should maintain the liquid pressure inside the trasfer pipe higher than that of my receiving vessel in order to avoid back pressure. am I right ?
'Since I am dealing with fluid dynamics after a very long time, I am not able to initiate the problem.
I tried Benoulli's principle, but since the driving force is due to the rotational force inside the bowl and not gravitational force, I am not able to use bernoullis theorem to calculate the static and dynamic pressure inside the centripetal pump.
A solution to this will be appreciated.
Thanks
