Water flows through a 180 degree reducing bend, as shown. The discharge is 0.25 mA3/s, and...
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...
(15 points) Water at 20 °C flows through a 180° pipe bend. Pressures and diameters of the pipe at point 1 and two are given as P,-350 kPa, D1-30 cm, P., 120 kPa, and D2 . 8 cm. Neglecting the pipe and water weight, answer the following questions. Patm is 100 kPa, and the total reaction force in the x direction, F., is measured as-20 kN. 4. P-100 kP a. What are gage pressures at point 1 and 2 b....
Water is flows through a nozzle at a rate of 18 ft/s (Q) and discharge into the atmosphere. The diameters Di 15 in. and D2- 5.5 in. The pressure measured at section 1 is P1-3100 1b/ft (gage). Determine the horizontal force required at the flange to hold the nozzle in place. Indicated the direction of the force (to the left or to the right). D2
Problem 1 (30): Water (density p 999 kg/m') flows through a pipe bend and constriction as shown in the schematic. The pipe section is connected to input and output pipes at loc ations A and B. the inlet point A is located 1 m higher in elevation compared to the exit point B. The total loss d ue to pipe friction, bend, and constriction can be approximated as EU = etY2 with et = 2.1 2 Find the total force...
Water is flowing through a horizontal pipe with diameter, D1, at a velocity, V1, and under a pressure, P1. It enters a 900 reducing bend (Shown in grey in Fig 2) that connects to a vertical pipe of diameter, D2. The inlet of the bend is 50 cm above the exit of the bend (as shown in Fig 2). Axes for positive directions of x and z coordinates are provided. Figure 2 Side view of reducing bend from horizontal to...
summatize the following info and break them into differeng key points. write them in yojr own words apartus 6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
