Is My Method for Calculating Pressure Difference in a Venturi Meter Correct?

Click For Summary
SUMMARY

The discussion focuses on calculating the pressure difference in a Venturi meter using the given dimensions and a manometer reading. The inlet diameter is 25 cm, the throat diameter is 15 cm, and the mercury displacement is 12 mm. The relevant equations include Bernoulli's principle, mass continuity, and the pressure equation P = ρgh. The method for calculating the pressure difference is confirmed as correct based on these principles.

PREREQUISITES
  • Understanding of Bernoulli's principle
  • Knowledge of mass continuity in fluid dynamics
  • Familiarity with pressure calculations using P = ρgh
  • Basic concepts of Venturi meters and manometer usage
NEXT STEPS

Homework Statement


Water flows through a venturi meter, with an inlet diameter of 25cm and a throat diameter of 15cm. The pressure difference is measured using a manometer, which displaces the mercury by 12mm on the throat side.


Homework Equations


Bernoulli's
Mass continuity
P=rho.g.h

Is this correct? I have no answers available as its from a past paper. My exam is tommorow and I would just like to clarify that the method I have used to find the pressure difference is correct.

Thanks.

No one able to help with this?

My exam is tommorow morning and I wouldn't mind some closure on my quiery.
