directly proportional to pipe wall roughness and independent of Reynolds number

inversely proportional to Reynolds number and indpendent of pipe wall roughness

directly proportional to Reynolds number and independent of pipe wall roughness

Pirani Gauge

Bourdon tube

ionisastion gauge

Micro-manometer

more

same

less

more or less depending on size of glass tube

force of adhesion

atmospheric pressure

surface tension

force of cohesion

the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time

the magnitude and direction of the velocity do not change from point to point in the fluid

the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane

the direction and magnitude of the velocity at all points are identical

minimum

negative value

could be any value

maximum

cannot remain at rest under action of any shear force

has the same shear stress.at a point regardless of its motion

cannot be subjected to shear forces

always expands until it fills any container
