Question

1,2 please!!!

1. Identify five examples of an unsteady flow and explain what features classify them as unsteady 2. The velocity of water flow in the nozzle shown is given by the following expression: V = 26/(1 - 0,57,2 Where V = velocity in feet per second, t = time in seconds, x = distance along the nozzle, and L = length of nozzle 4 ft. When x = 0.5L and t = 3 s, what is the local acceleration along the centerline? What is the convective acceleration? Assume quasi-one-dimensional flow prevails. I ft diameter - L41 Water

Answer 1

O Examples of unsteady flow :- I waves of beaches due to periodic motion. (1) Value is closed at the discharge end. (1) Flowe therough pipe of variable diametre under A variable pressure because velouties keep changing with time (1) flow of water from compressor pump as the flow rate/ velocity fluctuates with time. to flow of tides in ocean due to very high velocity fluctuation.
