13.81 Consider the stagnation tube of Figure 13.6. If the uncer- tainty in the manometer measurement is 0.1 mm, calculate the ve- locity and the uncertainty in the velocity. Assume that C₂ = 1.00, Pair = 1.25 kg/m³, and the only uncertainty is due to the mano- meter measurement. nut S Stagnation tube Figure 13.6 Deflection

Elevation = 100 ft D¸ = 1 ft (1) l (1) e, = 1000 ft D2 = 1 ft lz = 500 ft B V Elevation = %3D 20 ft (2) D3 = 1 ft (3) Elevation = l3 = 400 ft O ft Three open reservoirs are connected by pipes as shown above. It is assumed that the pipe diameter is equal to the friction factor of 0.03. Because theratio of the LIDpipe is large, the minor losses are ignored. Determine the flow in or out of each reservoir!
