When a valve is open, the fluid flows through an expansion duct (see duct diagram infigure) following a velocity field with the following form:

When A Valve Is Open The Fluid Flows Through An Expansion Duct See Duct Diagram In Figure Following A Velocity Field 1 (3.16 KiB) Viewed 58 times

.
Find: (a) the acceleration of the fluid at the point (x, t) = (L, L/U)
(b) the instant of time when the acceleration is null at x = L.
