The SI unit of pressure is
pascal(Pa)
Which physical quantity is measured in bar
atmospheric pressure
Mention one factor on which atmospheric pressure depend
altitude/density of air
The pressure inside a liquid of density of d is
hdg
pressure is-------in all directions about a point in a liquid
same
Pressure of a liquid at a given depth is--------------to the density of liquid
directly proportional
State weather pressure is a scalar or vector
scalar
State weather thrust is a scalar or vector
vector
Which devise is used to measure the atmospheric pressure
Barometer
The pressure which is exerted by air around us is known as
atmospheric presssure
The atmospheric pressure at the earths surface is P1 and inside mine is P2.then how they are related
P1 < P2
------ is the pressure acting on a surface if a thrust of 1 N is applied in a unit area.
1Pa
The pressure at a depth in a fluid column does not depend on
the shape of the structure containing the fluid.
Pressure, for the same thrust, can be increased by decreasing
area
Normal atmospheric pressure(value)
101300 Nm-2.
The unit torr is related to the barometric height as:
1 torr = 1 mm of Hg
