  • Filter pumps are used to separate a mixture of liquids with different densities.
  • in filter pump when the speed increases the pressure descreases
  • Atomizer is a device for emitting water, perfume or other liquids
  • atomizers cab be seen in perfume bottles, engine carburetors etc
  • the pressure is reduced by the help of tub this reduction in pressure causes the liquid to rise into air stream
  • engine carburetor: a device that mixes fuel with air and delivers it to the engine with ideal volume
  • As air flows through the narrowed passage in the carburetor, its velocity increases, resulting in a decrease in pressure according to Bernoulli's principle ( engine carburetor)
  • The faster the air flow the lowee=r the air pressure
  • Carburetor: It's like a mixer for air and gas.
  • Bernoulli's principle: Says that faster-moving air has lower pressure.
  • Airflow acceleration: Air speeds up as it moves through the carburetor.
  • Pressure drop: As air speeds up, its pressure decreases.
  • Fuel atomization: Gas turns into tiny droplets in the low-pressure zone.
  • Mixture formation: Atomized gas mixes with fast-moving air.
  • Combustion: The mixture goes into the engine and burns to make power
  • Torricelli's theorem states that the speed of efflux is equal to the speed gained by fluid while falling through height h under the action of gravity
  • the pressure at both ends is same ( torricellis theorem)
  • Torricelli's theorem v=under root (2gh)​
  • a chimney works best when it is tall and exposed at air currents, which reduces the pressure at the top and forces the smoke upwards
  • An aerofoil is a special shape, like a curved wing or blade, that helps things like airplanes, helicopters, and wind turbines fly or move more efficiently. It's designed so that when air flows over it, it creates a force called lift that helps lift or propel the object.
  • The upper surface of an aerofoil has a smooth curve with no sharp edges. This allows the air to flow smoothly over the surface without any sudden changes in direction.
