Question

Penuieuiar to the streamlines: (1) True (2) False. iv). The continuity equation is a scalar equation: (1) True (2) False. v). Water exits a nozzle at a velocity V and strikes a flat plate which experiences a force of magnitude E. If the velocity is doubled the force on the plate will be: (1) F (2) 2F (3) 4F (4) 8F vi). When the velocity profle is uniform, the KE correction factor a is equal tor (1) 0 (2) 1 (3) 2. vii). Insertion of a pump into a flow causes which gradeline to rise abruptly? (1) EGL (2) HGL (3) Both. vii). Water is flowing in a pipe with velocity V 2m/s. The pipe empties into a large reservoir. If 9-10m/s2, the associated head loss is (1) 1 m (2) 0.5 m (3) 0.2m. ix). The viscous shear stress is written with two subscripts. Reading from left to right, the first denotes the orientation of the surface on which it acts, while the second gives the direction of flow: (1) True (2) False. x). The shear stress due to viscosity acts: (1) Along the surface (2) Normal to the surface. xi). If the convective contribution is dominant in the Navier-Stokes equation, the Reynolds number will be: (1) Small (2) Large. xi). Water is flowing in a pipe of dia 0.1 m and the Reynolds number has been calculated to be 10. The flow is likely to be (1) Laminar (2) Turbulent. xii). The convective acceleration term appears in the Navier-Stokes equation because: (1) Momentum flow in and out of CV may not be equal (2) Flow may be unsteady (3) Flow may be laminar. of A quantity such as the Reynolds number has no units and is useful because: (1) Enables scale up xiv). experiments (2) We don't have to worry about its numerical value. xv). Water in viscous flow is fowing through two pipes. (1) with dia dy and (2) with di dy such that dy
