What would be the effect on the result of the following systematic errors of measurement! a. The jockey weight in error by 0.001kg. b. The distance from the center of the vane to the pivot of the lever in error by 1mm. C. The diameter of the water jet emerging from the nozzle 0.1mm different from the nozzle diameter. It has heen assumed that the velocity in the let is uniform over the entire cross section.

C2. A conical tube is fixed vertically with its smaller end upwards and it forms a part of the pipeline. The diameter at the smaller end is 245 mm and at the larger end is 467 mm. The length of the conical tube is 1.8 m and the flow rate of the oil is 128 liters/s. The pressure at the smaller end is equivalent to a head of 9.7 m of oil. Considering the following two cases: (1) Neglecting friction, (without head loss) determine (i) the velocity at the smaller end in m/s, (ii) the velocity at the larger end in m/s, and (iii) the pressure at the larger end of the tube. (2) If a head loss (with head loss) in the tube is hL= 0.0153(V1-V2)2, where V1 is the velocity at the smaller end and V2 is the velocity at the larger end, determine (iv) the head loss in m of oil and (v) the pressure at the larger end of the tube.
