Описание: ⭐ Venturi Meter Class 11 Physics || Applications Of Bernoulli's Equation || By Danish Majeed

Welcome to Physics with Danish, your go-to channel for conceptual, clear, and exam-oriented Physics lectures for Class 11 (NBF/Federal Board).

In this lecture, Danish Majeed explains the Venturi Meter, one of the most important practical applications of Bernoulli’s Equation used to measure the speed or rate of flow of fluids.

📘 Concepts Covered in This Lecture

🔹 Introduction to Venturi Meter
A Venturi Meter is a device that measures the rate of flow of fluid (like water or air) through a pipe using pressure difference.
It works on Bernoulli’s Equation and Equation of Continuity.

🔹 Construction:
It consists of three main parts:
1️⃣ Converging Section – decreases the area of flow, increasing velocity.
2️⃣ Throat – the narrowest part where pressure is minimum and velocity is maximum.
3️⃣ Diverging Section – where the fluid returns to its normal pressure and speed.

🔹 Working Principle:
When a fluid flows through a constriction, its velocity increases and pressure decreases according to Bernoulli’s Theorem.
By measuring the pressure difference between the wide and narrow sections using a manometer, the velocity and discharge (flow rate) can be calculated.
🔹 Applications:
✅ Measuring flow rate in pipelines.
✅ Used in aircraft to measure airspeed.
✅ Used in chemical plants and power stations.
✅ Hydraulic and irrigation systems.

🔹 Key Assumptions:

Fluid is incompressible and non-viscous.

Flow is steady and streamline.

No energy loss due to friction.
