15. The fluid element has rotated by an angle without any deformation. See figure 4. This motion is called 16. The fluid element in the shape of a square (in Figure 4a) of side unity was initially in the position shown ad has undergone a shear deformation shown in Figure 4b in an infinitely small interval of time dt. In this interval of time, the fluid element line along the X-axis is subjected to an angular displacement dv/axdt, while the fluid element line along the Y -axis is subjected to an angular displacement Quſay dt. The descriptions describe a deformation called of the fluid element. dt Rp. . Figure 4a Figure 4b 17. In the figure above, what is the mean angular displacement or mean rotation of the fluid element? Write the equation 18. If there is no rotation, what is the equation? 19. The quantity of the fluid flowing per unit of time across any section of a pipe or conduit is called the rate of flow or discharge. 20. How do you quantify the fluid flowing per unit of time across any section of a pipe or conduit? What's the equation?
