8. (10 points extra credit) Consider the figure shown below. It shows a U-shaped mercury manometer (a device for detecting pressure differences) that is attached to a pipe along which water is flowing from left to right. The water pipe has a circular cross-section. At A the diameter of the water pipe is 5.6 cm and the speed of the water is 2.80 m/s. At B the diameter of the pipe is 3 cm. The fluid in the manometer is...

Air at 100 kPa and density of 1.2 kg/m3 flows upward through a 5-cm diameter inclined duct at a rate of 50 L/s. The duct diameter is then reduced to 4 cm through a reducer. The pressure change across the reducer is measured by a water manometer. The elevation difference between the two points on the pipe where the two arms of the manometer are attached is 0.1 m. Determine the differential height between the fluid levels of the two...

The transfer of wastewater from a shallow reservoir to an underground reservoir is done using gravi ty-driven flow through a smooth-walled pipe (see diagram below). In order to control the flow, the diameter is reduced slightly between the top and vertical sections of the pipe (a simple practical ap plication of the Bernoulls equation). The smooth walls of the pipe generate very little shear, so that the flow follows the Bernoulli equation very nearly exactly. You may neglect pressure losses...

(c) Fuel oil, with a density of 870 kg m-, is pumped through a horizontal pipe, as shown in Figure Q2.2. The pipe is 100 mm in diameter and contains an orifice plate with a throat diameter of 40 mm. The pressure drop across the orifice is measured on a U-tube manometer, containing mercury with a specific gravity 13.6. The difference in levels of the columns is measured as 45 mm. The coefficient of discharge for the orifice plate Ca...
