An open water jet of circular cross-section and of 10 mm-diameter is deflected by a homogeneous rectangular block of thickness t, length of l and width of w (normal to the paper). the block weighs 10 n, the upstream velocity of the jet is given by u1 (r) = u (1- r2/r2) where r is the radial coordinate measured from the centerline of the jet. would the block tip under these conditions? if it does, calculate the magnitude of the horizontal force applied at corner a required for equilibrium. use: t = 20 mm, l = 120 mm, w = 200 mm, h = 80 mm,
