Upthrust is defined as the resultant thrust that a liquid uses to push up a body immersed in the liquid.
Its SI unit is Newton.
The factors that affect upthrust :
- Upthrust depends on the volume of object immersed in the liquid.
- Upthrust exerted by a liquid depends on the surface area of the solid immersed.
- Upthrust developed by a liquid depends upon the surface area of the solid immersed.
- Upthrust depends on the acceleration due to gravity of the place.
Pascal's Law :
Pascal's law states that if the pressure is applied to uniform fluids that are confined, the fluids will then transmit the same pressure in all directions at the same rate.
Instruments that are constructed on the basis of Pascal's Law :
- Hydraulic Brakes
- Hydraulic Press
- Hydraulic Jack
