Viscosity and Stokes’ Law

Most of the fluids are not ideal ones and offer some resistance to motion. This resistance to fluid… Read more Viscosity and Stokes’ Law

Dynamic Lift

Dynamic lift is the force that acts on a body, such as airplane wing, a hydrofoil or a spinning bal… Read more Dynamic Lift


The Venturi-meter is a device to measure the flow speed of incompressible fluid. It consists of a t… Read more Venturi-meter

Speed of Efflux: Torricelli’s Law

The word efflux means fluid outflow. Torricelli discovered that the speed of efflux from an open ta… Read more Speed of Efflux: Torricelli’s Law


Fluid flow is a complex phenomenon. But we can obtain some useful properties for steady or streamli… Read more BERNOULLI’S PRINCIPLE

Streamline Flow

So far we have studied fluids at rest. The study of the fluids in motion is known as fluid dynamics… Read more Streamline Flow

Hydraulic Machines

Let us now consider what happens when we change the pressure on a fluid contained in a vessel. Cons… Read more Hydraulic Machines

Atmospheric Pressure and Gauge Pressure

The pressure of the atmosphere at any point is equal to the weight of a column of air of unit cross… Read more Atmospheric Pressure and Gauge Pressure
