A drinking fountain projects water at an initial angle of 50 degrees above the horizontal, and the water reaches a maximum height of .150 m above the point of exit
a. Calculate the speed at which the water leaves the fountain.
b. The radius of the fountain's exit hole is 4.00 x 10^-3 m. Calculate the volume rate of flow of the water.
c. The fountain is fed by a pipe that at once point has a radius of 7.00 x 10^-3 m and is 3.00 below the fountain's opening. The density of water is 1.0 x 10^3 kg/m^3. Calculate the gauge pressure of the feeder pipe at this point.
The fuck is the volume flow rate? How do we find the velocity it exits the pipe at? How is it possible to find the pressure only knowing the radius the depth? This doesn't make any sense.
