$6\mathrm{.}66$ A horizontal reducing bend turnsthe flow of water $($p $=1000$ kg$/$m$3)$through $60\backslash$deg $.$ The inlet area is $0\mathrm{.}001$ m$\text{'},$ and the outlet area is $0\mathrm{.}0001$ m$?.$ The water from the outlet discharges into the atmosphere with a velocity of $55$ m$/$s$.$What horizontal force $($parallel to the initial flow direction$)$ acting through the metal of the bend at the inlet is required to hold the bend in place?
