A storm sewer is proposed to drain a 24 hectares drainage area shown in the figure below. With given data in the table below, determine x if the design discharge needed to convey 5-year peak discharge is 3.75m3/sec. (i=6270/(t+29))



C <-----------------> D


1Tt=15 min 2



For Site C For site D


Area (ha)=10 Area(ha)=14


C =0.6 C =0.45


Inlet time(min)=9 inlet time= X

Where did you get the t=12 and where did you base it? Why is it 10%? Thank you!

Evaluate the most probable values of angles A, B and C with the condition: A + B.The obscrved values are A= 68°12'36", B=58°01'16"and C= 53*46°12"

 


A standard HS truck move across a 25 m simple span. The wheel loads are P1 = 142 kN and P2 = 142 kN separated by 7.6 m, and P3 = 36 kN at 4.3 m from P2.

  1. Determine the maximum shear in kN.
  2. Determine the maximum moment in kN – m under P1.
  3. Determine the maximum moment in kN – m under P2.
