Consider water flowing in a circular section of a two-dimensional channel. Assume the velocity is uniform across the channel at 12 m/s. The pressure is 120 kPa at centerline (point 1). Determine the pressures at point 2 and 3 for the case of (a) flow in the horizontal plane and (b) flow in the vertical plane with gravity acting in the direction of 2 to 3.
