(a). A taper pipe of length 1000 m with diameters 1.0 m at the upper end and 0.3m at the lower end has water flowing through at the rate of 162 m* /hr. If the pipe's effective angle of inclination is 15°, find the pressure at the lower end given that the pressure at the upper end is 3 bar. (b). A vertical wall is 10 m high. A jet of water issues from a nozzle situated at a horizontal distance of 20 m from the wall with a velocity of 25 m/s. Find the angle of projection so that the jet just clears the top of the wall. For the angle(s) obtained, what will be the height attained by the jet if the nozle is positioned 12 m from the wall?
