Question

A flow is characterized by a repeating periodic flow with a period of 2 s and an upward slope of Delta x: Delta y = 1: 1 followed by a downward slope of -1: 1 as demonstrated in the streamline plot shown below as with the upward slope lasting 1 s and downward lasting 1 s. The magnitude of the velocity, whether upward or downward is 10 m/s. Given that the path line shown below is for a fluid parcel released at t = 0 and plotted over 2.5 s. re plot the path line with x and y axes labeled with tic marks every 5 m. create a similar streak line plot for t - 2.5 s. The figure below shows a side stream with a steady velocity of 1 m/s entering a river section perpendicular to the river flow which is a linearly changing velocity of v = 0 to 1 m/s over 5 s. or v = (1 m/s) t/5 for t in s. Assuming no mixing of the side stream with the river, and that the net velocity of the side stream moving into the river being in the vector sum of the never and the constant velocity component due to the side stream, sketch streamlines at 0.2.5 s. and 5s. sketch a path line over 0 to 5s. plot a streak line at t = 5s over x from 0 to 5 m.

Explanation / Answer

from the given data lets place time on y axis and velocity and axis

then we get
