g The space between two coaxial cylinders is flled with an incompressible fuid at constant temperature. The radii of the inner and outer wetted surfaces are nR and R, respectively. The angular velocities of rotation of the inner and outer cylinders are 1i and 1o. Determine the velocity distribution in the fuid, and the torques exerted by the fuid on the two cylinders needed to maintain the motion

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
