Answer:
0.245 m^3/s
Explanation:
Flow rate through pipe a is 0.4 m3/s Parallel pipes have a diameter D = 30 cm => r = 15 cm = 0.15 m Length of Pipe a = 1000m Length of Pipe b = 2650m Temperature = 15 degrees Va = V / A = (0.4m3/s) / (3.14 (0.15m)^2) = 5.66 m/s h = (f(LV^2)) / D2g (fa(LaVa^2)) / Da2g = (fb(LbVb^2)) / Da2g and Da = Db; fa = fb LaVa^2 = LbVb^2 => La/Lb = Vb^2/Va^2 Vd^2 = Va^2(La/Lb) => Vb = Va(La/Lb)^(1/2) Vb = 5.66 (1000/2650)^(1/2) => 5.66 x 0.6143 = 3.4769 m/s Vb = 3.4769 m/s V = AVb = 3.14(0.15)^2 x 3.4769 m/s = 0.245 m^3/s
It is important because now a days we all need help from engineers
Did not engineer cables factoring wind shear
Wooden 2 X 8's, 10's, or 12's that run parallel to one another and support a floor or ceiling, and supported in turn by larger beams, girders, or bearing walls- <u>Joist</u>
Explanation:
- Wooden 2 X 8's, 10's, or 12's that run parallel to one another and support a floor or ceiling, and supported in turn by larger beams, girders, or bearing walls- <u>Joist</u>
- A point where a bearing/structural weight is concentrated and transferred to the foundation-<u>Point Load</u>
- Includes all exterior walls and any interior wall that is aligned above a support beam or girder-<u>Load Bearing Wall</u>
- Plywood substitute made of coarse sawdust that is mixed with resin and pressed into sheets-<u>Particleboard</u>
- The replacement of excavated earth into a trench around or against a basement/crawl space foundation wall- <u>Backfill</u>
- Continuous 8m" or 10" thick concrete pad installed before and supports the foundation wall or monopost-<u>Footing</u>
- Ribbed steel bars installed in foundation concrete walls, footers and poured in place concrete structures designed to strengthen concrete-<u>Rebar</u>
- The end, upper, triangular area of a home, beneath the roof-<u>Gable</u>
- A manufactured 4X8 wood panel made out of 1-2 wood chips and glue. Often used as a substitute for plywood-<u>OSB</u>
- The incline slope of a roof or the ratio of the total width of a house-<u>Pitch</u>
- A manufactured structual wood beam. It is constructed of pressure and adhesive wood strands of wood-<u>Microlam</u>
