6.4 Water flows in a circular channel as shown in the figure. The velocity is 12 m/s and uniform across the channel. The pressure is 120 kPa at the centerline (point 1). Determine the pressures at points 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.
