I am trying to understand the fundamental concepts of fluid dynamics. Lets say I have
1.The larger end has a diameter of 8cm and Area 50.26cm2.
2.The small side has a diameter of 3cm and Area 7.0685cm2.
3.The water jet exerts a force of 87N at the smaller end.
- Water Entering the pipe is art 20degrees C
I know that :
1 - There's a change in cross-sectional area: A1 > A2
2 - Thanks to conservation of mass, (1) implies V2 > V1
3 - Thanks to Bernoulli, (2) implies p2 < p1
I am assuming a steady flow and no frictions and that the liquid is water, how can I find the velocity at the smaller end of the nozzle ?
I have calculate the Pressure using P = F/A to get a P2 of 12.3N/cm2.
However I am getting stuck in calculating P1 and V2
I have tried using Bernoulli's Equation however, I do not know P1 which is leaving me with more than one unknown.
Any Help would be appreciated.
