Water is flowing of the fire hydrant

Water is flowing from the 150-mm-diameter fire hydrant with a velocity vB = 15 m/s. Determine the horizontal and vertical components of force and the moment developed at the base joint A, if the static (gauge) pressure at A is 50 kPa. The diameter of the fire hydrant at A is 200 mm Pv = 1 Mg/m3.
