Water, which has density r, is pumped (at high pressure) at rate Q into the left end of a cylindrical pipe. Q is the mass flux (the mass per time pumped into the pipe). The radius of the left end of the pipe is r1. The pipe gradually narrows and curves as shown below. At the other end of the pipe, the radius is r2. The right end of the pipe is at the same height as point B. Express your answers symbolically in constants listed above, and g. (a) How high into the air, above the right end of the pipe, does the water shoot? Hint: Recall kinematics. (b) If the air pressure is Pair, then what is the pressure exerted by the water on the wall of the pipe at point B? Hint: Recall Bernoulli's law.
