3. Fluid "jetser-M. The October 1993 Journal of Engineering Education gives an account of a competition in the Civil Engineering department at Oregon State University. There, "Students design and build a fluid jetser powered solely by water from a reservoir connected to a nozzle and mounted on a wheeled platform." A possible configuration for such a "fluid jetser" as shown below. (40 Points) (Relative to nozzle) h Neglecting fluid friction, use Bernoulli's equation to derive an expression for v (the exit velocity of the water, relative to the nozzle) in terms of the current value of the height differential h. If the cross-sectional area of the nozzle is A, and the density of water is p. give an expression for the mass flow rate m that is leaving the nozzle. Then perform a momentum balance on the moving jetser, as seen by a stationary observer. Hence, derive an expression for the acceleration du/dt in terms of any or all of h, A, F (the drag force), u, M (the current mass of the vehicle), p, and any physical constant(s) that you think are necessary. 3.
