Document Summary
Navier-stokes equation is (a) a differential form of the continuity equation; (b) a differential form of the momentum equation. (c) a differential form of the energy equation. (3). Shaft work . (a) is the same as flow work; (b) is usually the work associated with a pump or turbine ; (c) is the work done by pressure forces. (4). The hydraulic grade line is . (a) the profile of the piezometric head, )2/(2 (b) is a plot of the total head, g (c) the same as the energy grade line. 1: (20 pt): suppose there is a flow with velocity u passing around a sphere, shown in. Find the sphere drag force f on the flow from the view of dimensional analysis. And are the density and dynamic viscosity of the fluid, respectively. F = f ( , , u, d: the 5 variables involve 3 basic dimensions, [m], [l] and [t].
