Bernoulli's fluid flow in a tube [desperate]

Click For Summary
SUMMARY

The discussion centers on solving a fluid dynamics problem using Bernoulli's equation, specifically the equation P + (1/2)pv² + pgh = constant. The user expresses frustration over not being able to arrive at the correct answers due to missing parameters, particularly the diameters of the pipe and the exit pressure. It is established that to solve the problem, one must apply the conservation of mass to determine the final velocity of the fluid, assuming incompressibility, which allows for the calculation of all but one term in Bernoulli's equation.

PREREQUISITES
  • Understanding of Bernoulli's equation and its components
  • Knowledge of fluid dynamics principles, particularly conservation of mass
  • Familiarity with the concept of incompressible fluids
  • Ability to interpret and manipulate equations related to fluid flow
NEXT STEPS
  • Study the application of Bernoulli's equation in various fluid flow scenarios
  • Learn how to calculate fluid velocity using the conservation of mass
  • Research the impact of pipe diameter on fluid dynamics
  • Explore methods for determining exit pressure in fluid systems
USEFUL FOR

Students preparing for exams in fluid dynamics, engineers working with fluid systems, and anyone seeking to understand the application of Bernoulli's equation in real-world scenarios.

It is 2 days before final exam and I don't even know how to solve this. I am so screwed.

This problem cannot be solved without the diameters of the pipe, or the exit pressure. To be honest, I'm not sure what you could have tried to get an answer.

IF you have the diameters. You use the conservation of mass to obtain the final velocity, assuming the fluid is incompressible, so mass flow is constant. From there, you have all but one (exit pressure) term in Bernoulli's.
