6.43 Water (p = 1000 kg/m3) flows through a nozzle and discharges into the atmosphere at section 2. The cross section areas are A, = 250 cm? and A, = 20 cm?. The mass flow rate is 28 kg/s, h = 150 cm, and 0 = 20°. The weight of the water and the nozzle can be neglected. %3! Problem 6.43 In newtons, what are the horizontal and vertical force components (F, Fy) that are needed to hold the nozzle in place? a. -2500, 130 b. -3700, 410 c. -700, 21o d. -1200, 32o е. - 980, 140
