(Problem) Water (p = 998 kg/m) flows steadily through the 180 elbow shown below. The volumetric flow rate is 8.2 x 10-2 m/s, and the water discharges to the atmosphere. The pipe diameters at sections (1) and (2) are 11 cm and 7 cm, respectively. Properties can be assumed uniform over the inlet and outlet, and losses and elevation changes may be ignored. Determine the magnitude and direction of the horizontal force that must be applied at the flange connection at (1) to hold the elbow in place. You need to apply Bernoulli's equation at some point to determine gauge pressure at (1) which is needed in the Momentum Equation. V (2)
