Need help with this engineering problem.
Extracted text: Required information When a valve is opened, fluid flows in the expansion duct for the given figure according to the approximation V = iU(1 – ) tanh NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part u(x, t) jx=0 ix=L For the given approximation, the fluid acceleration becomes zero when () = 1.146 . Does the fluid acceleration become positive after this condition? Yes or No
