Water flows through the horizontal 90° reducing bend shown in plan in Figure 3. The pressure at inlet ① is 150 kPa (gauge). Neglecting losses in the bend and taking atmospheric pressure outside the bend, determine (a) the gauge pressure at outlet ② (in kPa), (b) the x-component of the force exerted by the water on the bend (in kN), and (c) the magnitude of the resultant force exerted by the water on the bend (in kN).
