Calculating Air Pressure, Velocity at Venturi Tube Inlet/Throat/Outlet

Click For Summary
SUMMARY

The discussion focuses on calculating air pressure, velocity, and dynamic pressure at various points of a venturi tube with specified diameters: 3.0 inches at the inlet, 1.5 inches at the throat, and 3.5 inches at the outlet. Utilizing the principles outlined in "Fluid Mechanics" by RK Rajput, participants are guided through the necessary equations, including Bernoulli's equation and the continuity equation, to derive local air pressure and velocity at each section of the tube. The calculations are performed under standard day conditions at sea level, ensuring accurate results for practical applications.

PREREQUISITES
  • Understanding of Bernoulli's equation
  • Familiarity with the continuity equation in fluid dynamics
  • Knowledge of standard atmospheric conditions
  • Basic proficiency in unit conversions (inches to meters)
NEXT STEPS
  • Study Bernoulli's equation in detail for fluid flow analysis
  • Learn about the continuity equation and its applications in fluid mechanics
  • Research the effects of diameter changes on fluid velocity and pressure
  • Explore practical applications of venturi tubes in engineering
USEFUL FOR

Engineering students, mechanical engineers, and professionals involved in fluid dynamics and flow measurement will benefit from this discussion.

Im a new to this site because my have a question that i don't know how to answer and it really confusing me. If it possible, can you guys show me step by step on how to solve it.

A venturi tube has an inlet diameter of 3.0 inches, a throat diameter of 1.5 inches and an outlet diameter of 3.5 inches. (at standard day conditions and sea level).
What is the local air pressure, dynamic pressure, total pressure and local velocity at the inlet, throat and outlet point.
