4) Consider the steady, two-dimensional velocity field given by u = 0.5+0.8x and ", -1.5-0.8y, where lengths are in units of m, time in s, and velocities in m/s. Calculate the various kinematic properties, namely, the rate of translation, rate of rotation, linear strain rate, shear strain rate, and volumetric strain rate. Verify that this flow is incompressible. 5) Water is flowing from a hose attached to a water main at 400 kPa gage (Fig.5). A child places his thumb to cover most of the hose outlet, causing a thin jet of high-speed water to emerge. If the hose is held upward, what is the maximum height that the jet could achieve?
