an inclined manometer is connected to a pitor tube to measure the velocity at the center of a circular duct. If the inclined manometer measured 2.3 inches of water and the minimum division on the manometer scale is 0.04 inches of water. What is the uncertainty of the velocty at the center of the pipe in m/s
