The nozzle in the figure is shaped such that the velocity of flow varies linearly from the base of the nozzle to its tip. At the base, diameter is D and x=0, and at the tip, diameter is d and x=L. The velocity at any distance x is assumed to be the same over the cross section. The velocity at the base is 2t (ft/s) and at the tip is 5t (ft/s), where t is tiime in seconds (s). L = length of nozzle = 4ft.
A) What will be the local acceleration at x=0.25L when time t=4 seconds?
B) What will be the convective acceleration at x = 0.25L when time t=4 seconds?
