Air flows steadily along a streamline from point (1) to point (2) with negligible viscouseffects. The following conditions are measured: At point (1) z1 = 2 m and P1 = 0 N/m2; at point (2)z2 = 10 m, P2 = 20 N/m2, and v2 = 0 m/s. Based on this information, what condition exists at point(2) and what type of streamline is this? Determine the velocity at point (1) in m/s. The specificweight of the air is 12.1 N/m3
