4. A reducing elbow is used to deflect water flow at a rate of 30 lbm/s in a horizontal pipe upward by an angle 30° from the flow direction while accelerating it. The elbow discharges water into the atmosphere. The diameter of the elbow is 4 inch at the inlet and 2 inch at the exit. The elevation difference between the centers of the exit and inlet is 40 inch. The mass of the elbow and the water in it...

A 10 cm, 90° elbow in a horizontal pipe directs flow of water upward at a rate of 40 kg/s. The elevation difference between centers of the pipe exit and the inlet to the elbow is 50 cm. The weight of the elbow and water can be neglected. The momentum flux correction factor is 1.03 at both elbow inlet and outlet. Find: a. gauge pressure at the inlet to the elbow in kPa b. magnitude of anchoring force need to...

4. An old, rough-surfaced, 2-m-diameter concrete pipe with a Manning coefficient of 0.025 carries water at a rate of 5.0 m'/s when it is half ful. This pipe is to be replaced by a new smooth pipe with a Manning coefficient of 0.012. Determine the diameter of the new pipe if it also is to flow half full with a flow rate of 5.0 m'/s Water initially flowing in the horizontal section of pipe of diameter 12.00 cm shown in...

A converging elbow turns water through an angle of 60° in a horizontal plane. The flow cross-sectional diameter is d1-200mm at the elbow inlet, and d2-100mm at the outlet. The elbow flow passage volume is 0.02m3 between sections (1) and (2). The water volumetric flow rate is 40 Liters/s and the pressure measured at the inlet is 150 kPa. Neglecting the weight of the elbow, calculate: a- The...

4. (10 points) Water flows steadily through a reducing elbow before being released to atmosphere, as shown in the figure below. The average velocity at the inlet is U - 1 m/s. The diameter at the outlet D2 = 0.1 m is less than the diameter at the inlet D = 0.15 m, such that the flow accelerates through the elbow. The elbow is smooth and short, such that the effect of friction is negligible. The elbow is in horizontal...

2. A reducing pipe bend turns a water flow of 60 litre/s through 60° in a horizontal plane. The pipe inlet diameter is 100 mm while the exit diameter is 60 mm. If the water pressure in the inlet plane is 300 kPa (abs), use Bernoulli's equation to calculate the pressure in the exit plane 104.0 kPa (abs) ] Find the magnitude and direction of the force exerted on the bend by the water. (Take...

The required water flow rate in the 6 cm diameter 30-meter long circular pipe in the diagram below is 12 liters per second. The water temperature is 4 °C and the flow discharges into the atmosphere at a pressure of PB = 100 kPa. The flow is fully developed turbulent flow and there is no elevation change. The surface of the wall has become degraded due to pitting and deposits such that there is a surface roughness with a height...

A 45° reducing elbow (2 ft diameter inlet by 1.5 ft diameter outlet) transfers air steadily in the horizontal plane. What restraining forces in the x and y directions are needed to hold the fitting in place? The pressure throughout is relatively constant at 3 psig, and the air may be treated as incompresible at standard atmosphere. Uniform Velocity Xt ft

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
