Part 1 Correct. Water flows through a horizontal, pipe bend as is illustrated in the figure below. The flow cross section area is constant at a value of 9000 mm2. The flow velocity everywhere in the bend is 15 m/s. The pressures at the entrance and exit of the bend are 210 and 149 kPa, respectively. Calculate the horizontal (x and y) components of the anchoring force needed to hold the bend in place (a) What is the density of...
