Neglecting all pressure losses, determine the height H and flow rate Q of a water jet (рв = 1000 kg/m3) with an initial diameter d = 25 m at the exit from a nozzle of length h = 0.25 m. The jet is ejected by a vertical tube with a diameter of D = 500 mm and length h0 = 3 m, which is fed from a reservoir with a constant level under excess pressure рм = 5 N/cm2 = 5•104 N/m2 above the free surface (Fig. ).
