fluid pressure upthrust and flotation

Introduction - The pressure exerted by a liquid on the base of the container depends on the vertical height of the liquid over it not on the area of cross-section. As one goes deeper in the swimming pool, the pressure on the ear drum is found to increase. A column of mercury exe..

Principle of Flotation - When a body floats in a fluid, it displaces an amount of fluid equal to its own weight. The apparent weight of a floating body is zero. Hydrometers and submarines use the principle of flotation. Words to Remember:- Fluid, Atmosph..

Any liquid or gas produces upthrust. For example, the upthrust of air keeps a hot air balloon u..

When the volume of body fluids decreases below normal due to profuse sweating during heavy exercise or high temperature or excessive bleeding or a prolonged delay in fluid intake, the rate of ultra filtration is decreased due to decreased blood volume and low hydrostatic p..
