Bernoulli's Equation- on a jet nozzle

Click For Summary
SUMMARY

The discussion focuses on deriving equations related to a jet of liquid flowing from a nozzle, utilizing Bernoulli's Equation. The participants successfully derived the jet speed at the nozzle exit as v = sqrt(2(Po - B)/ρ) and the speed at a vertical distance z below the nozzle as v = sqrt(2(Po - B - ρgz')/ρ). The cross-sectional area A of the jet at distance z is determined using the continuity equation, leading to the conclusion that A2 = A0 * sqrt(ρgz). The importance of maintaining unit consistency and understanding algebraic manipulations is emphasized throughout the discussion.

Would you subtract the square root from the right hand side to get A2 on its own, then group like terms?

Subtracting the radical does not get A2 alone. You have missed something in your algebra studies.
 
  • #33
Can you help me to what the equation would work out to?
