4. (10 points) Water flows steadily through a reducing elbow before being released to atmosphere, as...
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
3. Water flows through a circular channel that has a diameter of d= 75 mm at both the inlet and outlet, as shown below. The fluid enters with uniform velocity U = 7.5 m/s. The channel makes a 90° bend that distorts the flow to produce the velocity profile at the outlet described by the function, v(r) = Vmax ( 1 -722 Assume steady, incompressible flow. Density of water is 1000 kg/m² a) Find the value of Vmax. b) Find...
Water flows steadily through a curved duct that turns the flow through angle @= 135º, as shown in Fig. 3. The cross-sectional area of the duct changes from A1 = 0.025 m² at the inlet to A2 = 0.05 m’ at the outlet. The average velocity at the duct inlet is V1 = 6 m/s. The momentum flux correction factor may be taken as B1 = 1.01 at the duct inlet and B2 = 1.03 at the its outlet. The...
Water (p = 1,000 kg/m?) flows steadily through a 90° elbow and exits as a free jet through a nozzle, as shown below. The measured upstream gage pressure is 800 kPa. Neglect body forces and viscous effects, and disregard the height of the elbow/nozzle combination. The water velocity at any cross section is assumed to be uniform. However, the water velocity inside the elbow is not negligible compared to that in the nozzle. Consider the following: Determine the velocities V,...
Water at 60 °F flows through the elbow as shown below and is then injected to the atmosphere through a nozzle (on a horizontal plane). The pipe diameter is Di = 4 in. while the diameter of the exit of the nozzle is D2 = 1 in. At a flow rate of Q = 245 gpm, the gage pressure at the section (1) where the flange locates is Pi = 34 psig. Neglect the weight of the water and elbow,...
please help...add sketch Water flows steadily through a curved duct that turns the flow through angle = 1359, as shown in Fig. 3. The cross-sectional area of the duct changes from A1 = 0.025 m’ at the inlet to Az = 0.05 m² at the outlet. The average velocity at the duct inlet is V1 = 6 m/s. The momentum flux correction factor may be taken as B - 1.01 at the duct inlet and B = 1.03 at the...
asap please, will rate! 3. Water flows steadily through a curved duct that turns the flow through angle 0= 135º, as shown in Fig. 3. The cross-sectional area of the duct changes from Aj 0.025 m² at the inlet to A2 = 0.05 m² at the outlet. The average velocity at the duct inlet is V1 = 6 m/s.

Water flows steadily through a curved duct that turns the flow through angle = 135 degrees, as shown in Fig. 3. The cross-sectional area of the duct changes from A1 = 0.025 m2 at the inlet to A2 = 0.05 m2 at the outlet. The average velocity at the duct inlet is V1 = 6 m/s.

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...
Show all work and answer all parts of the problem please. The 45 degree elbow nozzle discharges water into the atmosphere. The cross-sectional area of the elbow is 25 cm2 150 cm2 at the inlet and 25 cm2 at the exit. Velocity at point 1 and 2 are given as 2 m/s and 12 m/s 450 respectively.
