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 = 675500 Pascals, much higher than today's outside air pressure of 101300 Pascals. The pressure chamber is location at a height of y1 = 0.117 meters above the exit point. The exit point has a small opening with radius r = 0.0038 meters. Determine all the following: a) The velocity at which the water exits the Super Soaker: v2 = m/s b) The mass flow rate through the exit: kg/sec c) The volume flow rate through the exit: m3/sec

We would like to calculate the minimum pressure required to force plasma from the heart to the top of the head. For this analysis we will assume blood is a Newtonian, incompressible fluid. The distance from the heart to the top of the head is 0.5m. Assume the density of plasma to be 1065 kg/m3. The vein diameter is 0.95 mm. Assume friction can be neglected.
