SUMMARY

The discussion focuses on calculating fluid velocities in pipes with diameters of 150mm and 300mm, specifically for a scenario where water is delivered at a rate of 7500 liters per minute and a pressure of 820 kPa. The continuity equation, represented as m = p1A1v1 = p2A2V2, is confirmed as the appropriate method for solving the problem. Participants agree that understanding flow rate and cross-sectional areas is essential for accurate calculations.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Familiarity with the continuity equation in fluid mechanics
  • Knowledge of pipe flow characteristics
  • Basic skills in pressure and flow rate calculations
NEXT STEPS
  • Study the application of the continuity equation in various fluid flow scenarios
  • Learn about Bernoulli's equation and its implications for fluid velocity
  • Research the effects of pipe diameter changes on flow rate and velocity
  • Explore practical examples of fluid velocity calculations in engineering contexts
USEFUL FOR

Engineering students, fluid mechanics practitioners, and anyone involved in hydraulic design and analysis will benefit from this discussion.

Homework Statement



A pipe of 150mm bore is delivering water at a rate of 7500 liter/min at a pressure of 820 kPa. It connects via a horizontal, gradually expanding pipe, to a main of 300mm diameter. calculate the fluid velocities both in the main body of the pipe and at the outlet.

Homework Equations



m= p1A1v1 = p2A2V2


The Attempt at a Solution



Is the equation above correct to use for this problem. Thanks in advance.

Yup, if all you're concerned about is flow rate, then continuity is all you need assuming you have areas...which you do!
