1. A stationary curved vane deflects a 50 mm diameter jet of water through 150â—¦. Because of friction over the surface, the water leaving the vane has only 80% of its original velocity. Calculate the volume flow rate necessary to produce a fluid-dynamic force of 2000 N on the vane
2. A toy balloon of mass 86 g is filled with air of density 1.29 kg · m−3. The small filling tube of 6 mm bore is pointed vertically downwards and the balloon is released. Neglecting frictional effects calculate the rate at which the air escapes if the initial acceleration of the balloon is 15 m ·s−2
