What is it like to fly in a plane?
You will feel slight bumps during the flight, which is all part of the normal experience when in flight. You may feel turbulence, especially during inclement weather like thunderstorms and that, too, is a perfectly normal part of a plane ride.
What is Bernoulli’s principle Class 11?
Bernoulli’s principle formulated by Daniel Bernoulli states that as the speed of a moving fluid increases (liquid or gas), the pressure within the fluid decreases.
What does Torricelli’s Law describe?
Torricelli’s theorem, also called Torricelli’s law, Torricelli’s principle, or Torricelli’s equation, statement that the speed, v, of a liquid flowing under the force of gravity out of an opening in a tank is proportional jointly to the square root of the vertical distance, h, between the liquid surface and the centre …
Why is Venturimeter used?
A venturi meter is a measuring or also considered as a meter device that is usually used to measure the flow of a fluid in the pipe. A Venturi meter may also be used to increase the velocity of any type fluid in a pipe at any particular point. It basically works on the principle of Bernoulli’s Theorem.
What is Torricelli’s vacuum?
A Torricelli vacuum is created when a glass tube is filled with mercury and then upended in a vessel containing a level of mercury. The mercury in the tube falls to a level allowed by atmospheric pressure. The vacuum at the top of the mercury column in the glass tube consists of mercury vapor.
What’s a barometer do?
Barometers. A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure.
Who is the inventor of barometer?
Evangelista Torricelli
Why mercury is used in barometer?
Mercury is commonly used in barometers because its high density means the height of the column can be a reasonable size to measure atmospheric pressure. A barometer using water, for instance, would need to be 13.6 times taller than a mercury barometer to obtain the same pressure difference.
Why is water not used in barometer?
Water is not a suitable barometric liquid because: (i) The density of water is low (103 kg m-3). Water barometer will support 10.4m of water at sea level. It is impractical to have such a long tube.
What is density of mercury?
13.6 g/mL
