To move large quantities of coal, sometimes it is pulverized and mixed with water and then pumped long distances in pipelines. Prior to pumping, the slurry is kept in a mixing tank that is open to the atmosphere. If the specific gravity of the slurry is 1.33, what is the pressure in the slurry 2 meters below the slurry surface?

3) As shown in the figure below, water (o 1.94 slugs/ ft') is pumped from a large tank (1) at a rate of 3 ft'/s through a main supply line to the top of an aeration column (2), which is a large free surface open to the atmosphere. The head loss through the supply line is 4 ft. In the acration column, the water is entrained with air as it moves downward via gravity through the column and exits to...
9. The absolute pressure in water at a depth of 5 m is 145 kPa. What is the absolute pressure in a liquid whose specific gravity is 1.34 at the same depth? Hint: Determine the atmaspheric pressure first 10. Water is pumped from a lake to a storage tank 30 m above at a rate of 55 L/s, while consuming 22.6 kW of electrie power to run the motor. Detemine the overall efficiency of the motor-pump unit. .A hydraulic power...
Problem 1. Water flows from a large tank through a smooth pipe of length 80 m. Both the tank free surface and jet exit are exposed to the atmosphere. Take the density of water p = 1000 kg/m3, dynamic viscosity of water u = 0.001 kg/m.s, atmospheric pressure = 100 kPa, and gravity = 9.8 m/s2. Calculate the volumetric flow rate through the pipe. Neglect entrance losses to the pipe. Hint: Consider the inlet and outlet sections of the pipe...

(Fluid mechanics) 2 of 3 Water, assumed inviscid and incompressible, flows steadily out of a large tank as shown in the adjacent figure. Above the water there is a 2-m layer of oil of specific gravity SG = 0.81 and the water outlet is located 0.7 m below the oil-water interface. Take the elevation reference (z = 0) at the outlet level. Determine: Oil, SG = 0.81 0.7 m Water 50 mm diameter a) Are the validity conditions of Bernoulli's...
1/9 1 Piping system (14 points) Water is pumped from a reservoir to a large receiver vessel which is maintained at p4 6 bar (absolute) through the operation of the pump and a high pressure nitrogen supply that bleeds into the tank through a regulator. The water enters through an opening at the top of the vessel. A drain is provided at the low point in the system. Elevations are as shown. All valves are gate valves (k = 0.15)...

(100 points) Water at 25°C is pumped at a rate of 0.075m'/s from a reservoir 20m above a pump to a free discharge (this means discharged to atmosphere) 35m above the pump. The pressure on the intake side of the pump is 150kPa and the pressure on the discharge side of the pump is 450kPa. The pipe between the reservoir and the pump is 3 meters of 5in diameter cast iron. From the pump to the discharge the pipe is...
