A cylindrical tank of water rotates about its vertical axis (Fig. P473). A PIV system is used
Question:
A cylindrical tank of water rotates about its vertical axis (Fig. P4–73). A PIV system is used to measure the vorticity field of the flow. The measured value of vorticity in the z-direction is –45.4 rad/s and is constant to within 60.5 percent everywhere that it is measured. Calculate the angular speed of rotation of the tank in rpm. Is the tank rotating clockwise or counterclockwise about the vertical axis?
