Which among the following is not an application of the Bernoulli?a)Sai...
Solution:

The Bernoulli equation is a fundamental principle in fluid mechanics that relates the pressure, velocity, and elevation in a fluid flow system. It is based on the principle of conservation of energy for fluid flow. The Bernoulli equation can be applied to various fluid flow problems, but not all applications are suitable for its use.

Explanation:

The Bernoulli equation can be applied to a wide range of fluid flow problems, including the following applications:

a) Sailing: The Bernoulli equation can be used to explain the lift force acting on the sails of a boat. As the wind flows over the curved surface of the sails, it accelerates and creates a lower pressure region on the side facing the wind. This pressure difference generates a lift force that propels the boat forward.

c) Flow through a sharp-edged orifice: An orifice is a small opening through which a fluid flows. When the fluid flows through a sharp-edged orifice, the velocity increases and the pressure decreases according to the Bernoulli equation. This principle is applied in various engineering applications, such as flow measurement devices.

d) Closing of tap water: When a tap is closed, the fluid flow is restricted, leading to an increase in velocity and a decrease in pressure according to the Bernoulli equation. This principle is used in faucets and valves to control the flow of water.

However, option B, flow through a venturi tube, is not an application of the Bernoulli equation. A venturi tube is a device used to measure fluid flow rate by creating a pressure difference. Although the Bernoulli equation is commonly used to explain the principle of a venturi tube, it is not directly applied to the flow through the venturi tube itself.

The venturi tube operates on the principle of conservation of mass rather than energy. It uses the narrowing of the tube to increase the flow velocity and decrease the pressure, which can be measured to determine the flow rate. The Bernoulli equation can be used to explain the pressure difference, but it is not directly applied to the flow through the venturi tube.

In conclusion, the correct answer is option B, flow through a venturi tube, as it is not an application of the Bernoulli equation.

This is mainly because, Bernoulli’s equation is applied only when the fluid is irrotational. It means that the stream lines are not supposed to intersect each other. Also, the equation does not take viscosity into account. Thus, the flow rate decreases when you close the valve.
