In Prob. 4.26 the velocity varies linearly with time throughout the nozzle. The velocity at the base is 1t (ft /s) and at the tip is 4t (ft /s). What is the local acceleration midway along the nozzle when t = 2 s?

Data from Prob. 4.26

The nozzle in the figure is shaped such that the velocity of the fluid varies linearly from the base of the nozzle to its tip. Assuming quasi-one-dimensional flow, what is the convective acceleration midway between the base and the tip if the velocity is 2ft /s at the base and 5ft/s at the tip? Nozzle length is 23 inches.
