1.A rectangular plate 5ft by 4ft is at an angle of 30 degrees with the horizontal, and the 5-ft side is horizontal. Find the magnitude of the force on one side of the plate and the depth of its center of pressure when the top edge is (a) at the water; (b) 1 ft below the water surface
2.Velocities in a 200-mm-diameter circular conduit, measured at radii of 0,36,64, and 87 mm were 7.0, 6.8, 6.1, and 5.0 m/s, respectively. Find the approximate values (graphically) of the volume flow rate and the mean velocity. Also determine the ratio of the mean velocity to the maximum velocity.
