Solving a problem in physics section 50 point 99 mechan

99. The nozzle of the fountain, jet authorizing vertical height H = 5 m, has the shape of a truncated cone tapering upwards. Diameter of lower section d1 = 6 cm, top - d2 = 2 cm. The height of the nozzle h = 1 m. Disregarding the air resistance and the resistance in the jet nozzle, define: 1) the water flow in 1 supplied a fountain; 2) the difference in pressure Ap in the lower section and the atmospheric pressure. Ρ = density of water 1 g / cm3.
