Fluid Dynamics: Cylindrical Bucket, Water Flow & Height Increase

Click For Summary
SUMMARY

The discussion focuses on the fluid dynamics of a cylindrical bucket with a height of 30.0 cm and a diameter of 10.0 cm, featuring a hole at the bottom with a cross-sectional area of 1.35 cm². Water flows into the bucket at a rate of 2.20×10⁻⁴ m³/s. The continuity equation is correctly applied, indicating that the flow rate in equals the flow rate out at steady state. However, the application of Bernoulli's equation in this context is incorrect, as it does not properly account for the relationship between pressure head and mass flow rate.

PREREQUISITES
  • Understanding of fluid dynamics principles, specifically continuity equation
  • Knowledge of Bernoulli's equation and its applications

A cylindrical bucket, open at the top has height 30.0cm and diameter 10.0cm. A circular hole with a cross-sectional area 1.35cm^2 is cut in the center of the bottom of the bucket. Water flows into the bucket from a tube above it at the rate of 2.20×10−4 m^3/s

How high will the water in the bucket rise?
Take the free fall acceleration to be = 9.80

What I've done is
A_1*v_1 (bottom) = A_2*v_2 (top)

So Q_2 = 2.2*10^-4 = A_2*v_2

(0.0135)v_1 = 2.2*10^-4

v_1 = 0.016296m/s
A_1 = 0.0135m^2
v_2 = 0.028011m/s
A_2 = 0.007853m^2

Then I did the bernoulli's principle, cancelling out some stuff
P_1 + 0.5ρv_1^2 + ρgh = P2 + 0.5ρv_2^2 +ρgh

It was here where I got confused, but here's what I did..
(0.5)(1000)(0.016296^2) = (0.5)(1000)(0.028011^2) + (1000)(9.8)h

Is this the correct way to do it? Because I'm totally unsure.. so thanks for your time

The idea is that the pressure head is related to the flow rate out of the bottom, and the height increases until the flowrate out matches the flowrate in. The use of Bernoulli's equation is not correct as applied.

Certainly the continuity equation applies (flow in = flow out in steady state, i.e. dh/dt = 0), but one must find the mass flow rate out in terms of the pressure head.
