Water discharges through a 6-inch diameter pipe then a 1-inch diameter pipe. Compute the flow velocity at point in the 6-inch diameter pipe. P-3000 polig A. 1.83 ft/s B. 11.03 ft/s C. 22.06 ft/s D. 231 ft/s d-6 in 20 ft d. 1 in Water Discharge to atmosphere 9. . A glass tube of 3/32 inches internal diameter is inserted into a water reservoir as shown in the figure below. The water rises in the tube as a result of surface tension effects. Calculate this height above the level of the water in the reservoir Water Note: surface tension is 0.005 bm for water-air surface at standard atmospheric conditions.
