Hydraulics & Fluid Mechanics Mercury is often used in barometer because it is the best liquid both (B) and (C) its vapour pressure is so low that it may be neglected the height of barometer will be less it is the best liquid both (B) and (C) its vapour pressure is so low that it may be neglected the height of barometer will be less ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics Two dimensional flow occurs when the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time the direction and magnitude of the velocity at all points are identical the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane the magnitude and direction of the velocity do not change from point to point in the fluid the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time the direction and magnitude of the velocity at all points are identical the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane the magnitude and direction of the velocity do not change from point to point in the fluid ANSWER DOWNLOAD EXAMIANS APP
