Q3/ Determine the uncertainty in velocity as a function of uncertainty in the head h when a pitot static tube is used for air velocity measurement along with an inclined tube manometer. Here, h is the displacement of the manometric liquid along the tube. The governing equation is: 1 z pu? = P1g h sin 0 (assuming pi » p(air)) Where 0 is the angle at which the arm of the manometer is inclined with respect to the horizontal and p, is the density of the manometric liquid. Hint:- P1, g and p are constants.
