Water (density = 1000 kg/m3) flows through a duct that makes a 180 degree U-shaped bend (see below). Assume that the fluid is incompressible through the duct and the velocity at the inlet is V1 = 24 m/s. Assume that the momentum-flux correction factor at both inlet (point 1) and outlet (point 2) is 2.1. The gage pressures are P1 = 120 kPa at the inlet and P2 = 248 kPa at the outlet of the bend. The inlet is...

Water at 20 C is steadily flowing through a diverging pipe section that is inclined by an angle of 30° with respect to the horizontal (See the figure) The total testing section length is 20 m long with an initial pipe diameter of 10 mm (Section 1) and final diameter of 20 mm (Section 2). The small diameter section shows a gage pressure of 100 kPa and average flow velocity 10 m/s. Other values will be obtained by reaching complete...

3. Water flows along a circular pipe and is turned vertically through 180° by a reducing bend as shown in figure 2. The rate of flow in the pipe is 20 litres/s, the pressure measured at the entrance to the bend is 120 kN/m3 and the volume of fluid in the bend is 0.1m3. What is the magnitude and direction of the force exerted by the fluid on the bend? Ignore any friction losses. (10 marks) 100mm P - 120kN/m2...

Water flows through a 180 degree reducing bend, as shown. The discharge is 0.25 mA3/s, and the pressure at the center of the inlet section is 150 kPa gage. If the bend volume is 0.10 mA3, and it is assumed that the Bernoulli equation is valid, what force is required to hold the bend in place? The metal in the bend weighs 500 N. 30 cm - 10 cm 15 cm

Part 1 Correct. Water flows through a horizontal, pipe bend as is illustrated in the figure below. The flow cross section area is constant at a value of 9000 mm2. The flow velocity everywhere in the bend is 15 m/s. The pressures at the entrance and exit of the bend are 210 and 149 kPa, respectively. Calculate the horizontal (x and y) components of the anchoring force needed to hold the bend in place (a) What is the density of...

Problem 5.4 A short circular pipe with diameter D, has water (p,u) flowing through it from left to right at a volumetric flow rate Q. At the exit a plug with diameter D2 that partially blocks the water flow is inserted (to provide upstream pressure pı (gage) to the pipe and/or to reduce flow rate). Both upstream pressure and flow rate can be measured. (a) Using the conservation equations (mass, momentum) in...

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...
