Water is flowing in a 200 mm pipeline fitted with a 45^o bend in a vertical plane. The diameter at the outlet of the bend is 500 mm. The pipe axis at the inlet is horizontal and the outlet is 1.5 m above the inlet. If the flow through the bend is 0.4 m³/s and a head loss of 0.5 m occurs in the bend, calculate the magnitudes and the directions of the resultant force the bend support must withstand. The volume of the bend is 0.070 m³ and the pressure at the inlet is 300 kN/m²

Oil (ρ = 925 kg/m3) is flowing through a pipeline at a constant speed when it encounters a vertical bend in the pipe raising it 4.0 m

Oil (ρ = 925 kg/m3) is flowing through a pipeline at a constant speed when it encounters a vertical bend in the pipe raising it 4.0 m. The cross-sectional area of the pipe does not change.a) What is the speed of the fluid at Point B?b) What is the difference in pressure (PB – PA) in the portions of the pipe before and after the rise?

A horizontal pipeline conveying oil (s = 0.8) contains a 60◦bend in which the internal diameter reduces from 200 mm to 100 mm. If the pipe joints on either side of the bend exert no restraint on it, what will be the force an anchorage must resist when the pressure head and the mean velocity of the ﬂuid at entry to the bend are 12 m and 3 m/s respectively? Find also the direction in which the force acts.

A ship is fitted with six-cylinder CI engine of 75 mm bore and 100 mm stroke. The engine has a brake power output of 110 kW at 370 rpm. The volumetric efficiency at this operating condition, referred to ambient conditions, of 1.013 bar and 20˚C is 80%. You have just fitted a mechanically driven supercharger which has isentropic efficiency of 0.7 and the pressure ration of 1.6. The supercharged version of the engine has a volumetric efficiency of 100% referred...

A pipe, 900 m long and 200 mm in diameter discharges water to the atmosphere at a point 10 m below the inlet level. With an inlet pressure of 40 kPa gauge, the flow rate is 40 litres/sec. At a point half way between the pipe inlet and outlet, a new tapping is made from which water is taken at a rate of 18 litres/sec. To what value must the inlet pressure be raised in order to maintain the same...

A long, straight horizontal pipeline of diameter 350 mm and effective roughness size 0.03 mm is to be constructed to convey crude oil of density 860 kg/m3 and absolute viscosity 0.0064 N s∕m2 from the oilfield to a port at a steady rate of 7000 m3/day. Booster pumps, each providing a total head of 20 m with an overall efficiency of 60%, are to be installed at regular intervals. Determine the required spacing of the pumps and the power consumption...

(THERMODYNAMICS) A vertical cylinder fitted with a frictionless piston contains 1.5 kg of H2O initially at 100 °C, 400 kPa. If the volume of the system reaches 0.5 m3, the piston hits a set of stops and is restrained from further upward travel. The system is heated to 200 C. (Use saturated water tables, steam tables, and superheated tables as necessary) a) If the piston reaches the stops, determine the temperature and pressure when the piston first touches but exerts no force...

An incompressible fluid is flowing through a vertical pipe with a constriction. The wide section is 2.00 cm in diameter and is at the top of the pipe. The pressure of the fluid in the wide section at the top is 200 kPa. The velocity of the fluid in the wide section is 4.00 m/s. The narrow section is located 4.00 m below the wide section. What is the diameter of the narrow section for the pressure of the fluid...

On a day when the water is flowing relatively gently, water in the Niagara River is moving horizontally at 4.5 m/s before shooting over Niagara Falls. After moving over the edge, the water drops 53 m to the water below. A) If we ignore air resistance, how much time does it take for the water to go from the top of the falls to the bottom? B) How far does the water move horizontally during this time?

In a sample of 200 Bend households, you nd that 110 have cable television. In a sample of 250 Portland households, you nd that 160 have cable television. You wish to know whether these data indicate that the percentage of Bend households (population 1) with cable is less than the percentage of Portland households (population 2) with cable. Use = 0:05 in the hypothesis test. 1. Set up the null and alternative hypotheses and perform test statistics using normal model. 2....
