A 45° reducing elbow (2 ft diameter inlet by 1.5 ft diameter outlet) transfers air steadily...
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...
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. The gage pressure at 1 is 73 kPa 150 em2 30 cm The elevation difference between the centers of the exit and the...
7. Air [R=1715 ft·lb/(slug R), cp = 6003 ft-lb/(slug-R)] flows steadily, as shown in the figure, through a turbine which produces 700 hp. For the inlet and exit conditions shown, estimate (a) the exit velocity V2 and (b) the heat transferred in Btu per hour. Hint: The specific enthalpy of an ideal gas is h = CAT. w,700 hp Turbomachine D = 6 in P = 150 lb/in? Ti - 300°F V = 100 ft/s D -6 in P2 -...
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...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
