Two dimensional flow occurs when 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 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 TRUE ANSWER : ? YOUR ANSWER : ?
Uniform flow occurs when the flow is streamline size and shape of the cross section in a particular length remain constant size and cross section change uniformly along length the flow is steady TRUE ANSWER : ? YOUR ANSWER : ?
The normal stress is same in all directions at a point in a fluid When there is no motion of one fluid layer relative to an adjacent layer irrespective of the motion of one fluid layer relative to an adjacent layer only when the fluid is frictionless only when the fluid is incompressible and has zero viscosity TRUE ANSWER : ? YOUR ANSWER : ?
True one-dimensional flow occurs when the magnitude and direction of the velocity do not change from point to point in the fluid the direction and magnitude of the veiocity at all points are identical the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane TRUE ANSWER : ? YOUR ANSWER : ?
The total pressure force on a plane area is equal to the area multiplied by the intensity of pressure at the centriod, if the area is horizontal the area is vertical the area is inclined All of these TRUE ANSWER : ? YOUR ANSWER : ?
For laminar flow in a pipe of circular cross-section, the Darcy’s friction factor f is directly proportional to pipe wall roughness and independent of Reynolds number directly proportional to Reynolds number and independent of pipe wall roughness inversely proportional to Reynolds number and indpendent of pipe wall roughness inversely proportional to Reynolds number and directly proportional to pipe wall roughness TRUE ANSWER : ?
