SUMMARY

The discussion focuses on calculating the velocity of water exiting a nozzle using fluid dynamics principles, specifically the Bernoulli equation and the continuity equation. The user provided dimensions of the nozzle and the force exerted by the water jet, which is 87N. Key equations discussed include P = F/A, A1V1 = A2V2, and the momentum balance equation F = ρv²A. The final calculated velocity at the nozzle exit was determined to be 11.1 m/s, confirming the application of fluid dynamics concepts in solving the problem.

PREREQUISITES
  • Understanding of Bernoulli's equation

but water also exert pressure on the plate contributing to the force
As I see it, the only force from the water acting on the plate is the force due to the water hitting the plate. The video in post #17 shows how to calculate this force.
