A pipeline conveys benzene from one point to the other. A gauge attached to line reads 150kPa. It is desired to check the gauge reading with benzene –over-mercury U-tube manometer.Determine the expected height difference of the mercury in the manometer; if on one endthe manometer is open to the atmosphere and on the other end where the gauge pressure isconnected there is a 3 cm height of benzene above the mercury meniscus. (benzene densityis 876 kg/m3 and mercury 13600 kg/m3)

A U-tube manometer is connected between two pipes as shown below. One pipe contains carbon tetrachloride at 13 kPa gauge, while the other pipe contains oil at 172 kPa absolute. Determine the height, h, in mm. Assume barometer reads 0.9 atm. Carbon tetrachloride SG = 1.6 4m Oil SG 0:8 h

The speed v at which a rigid sphere falls through a viscous fluid depends on the difference in density between the sphere and the fluid, Ap, the radius of the sphere, a, and the viscosity of the fluid, 7, and is given by 2 gApa? v = 9 where q is the acceleration due to gravity. (a) East Coast beaches are dominated by quartz sand. A medium-sized grain of sand has a radius of 0.5 mm. The density of quartz is 2.65 g/cc (2650 kg/m³); the density of water is about 1 g/cc (1000 kg/m³). The viscosity of water at 20°C is 10-3 Pa s. The acceleration due to gravity is about 9.81 m/s². How long will it take for the grain of sand to sink through 10 m of water? (b) How fast does a sphere of radius 1 cm fall compared to a sphere of radius 0.5 mm in the same fluid? (c) Where a stream enters a pond, it is often observed that coarser sediment such as gravel is deposited near the mouth of the stream, while finer sediments such as sand and silt are deposited farther into the pond. Explain this…

As shown in Figure D, three water reservoirs are connected by three pipes. The diameters in each pipe is 1 ft and the Fanning friction factor in each pipe is 0.02. The effective lengths of each pipe are given in the Figure along with other relevant data. Determine the flow rate into or out of each reservoir as well as the Reynolds number in each pipe. (Hint: Start the computations by assuming that the water flows into reservoir B).
