Aliquid flowing from a vertical pipe has a very definite shape as it flows from the pipe. to get the equation for this shape, assume that the liquid is in free fall once it leaves the pipe. just as it leaves the pipe, the liquid has speed v0 and the radius of the stream of liquid is r0.
a) find an equation for the speed of the liquid as a function of the distance y it has fallen.
b)combining this with the equation of continuity, find an expression for the radius of the stream as a function of y.
c)if water flows out of a vertical pipe at a speed of 1.20 m/s, how far below the outlet will the radius be one-half the original radius of the stream?
