Education, Karnataka Examination Illustration The weight of the plastic bag full of air is same as that of the empty bag because the upthrust is equal to the weight of the air enclosed. Physics Wallah's main focus is to make the learning experience as economical as possible for all students. When velocity of fluid is less than its critical velocity then the flow of liquid is determined by its viscosity, its density has no effect on its flow. Mechanical Properties of Fluids, NCERT chapter 10 for class 11 Physics, covers the concepts and principles relating to these mechanical properties. The direction and magnitude of the velocity at all points are identical. This is called laminar motion of the liquid. The floating body is in stable equilibrium when the metacenter is above the centre of gravity (centre of gravity is below the centre of buoyancy). When any body is immersed (totally or partially) in a liquid it appears to lose part of its weight and the apparent loss of weight is equal to the weight of liquid displaced. For non-viscous, incompressible, streamline flow of fluids the sum of pressure per unit volume, potential energy per unit volume and Kinetic energy per unit volume remain constant. Open-tube manometers have U-shaped tubes and one end is always open.

NEET MCQ Books for XI th & XII th Physics, Chemistry & Biology. JEE Main, About A fluid is a state of matter that yields to sideways or shearing forces. Power is the amount of work which is done per unit of time; that is, power is the rate at which work is done. When the velocity of liquid is more than its critical velocity then its flow is determined by its density, where viscosity has little effect on its flow. Samuel J.
