The Super Soaker XP30 is a marvel of hydraulic dispersion weaponry. By pumping on the handle, you charge the chamber to high pressure. The pressure is maintained until you pull the trigger at which point the water (? = 1000 kg/m3) is released at high velocity.You have charged your pressure chamber to an absolute pressure of P1 = 697500 Pascals, much higher than today's outside air pressure of 101300 Pascals. The pressure chamber is location at a height of y1 = 0.103 meters above the exit point. The exit point has a small opening with radius r = 0.0033 meters.Determine all the following:The velocity at which the water exits the Super Soaker: v2 = m/sThe mass flow rate through the exit: kg/secThe volume flow rate through the exit: m3/secNOTE: You may treat the water chamber as a "tank" and approximate the water velocity there to be zero.

QUESTION 14 The fan of a turbofan engine is tested at high speed. The flow approaches the fan tip at a relative Mach number M1rel = 1.19. An oblique shock forms at the fan tip leading edge, with a shock angle B = 87 degrees. Use cold-air- standard assumptions and the two-dimensional oblique shock formulae to determine the relative Mach number M2rel after the shock. State your answer to two decimal places. Partial credit is awarded for a reasonable approximation to the correct numerical answer. %3D
