Offshore oil exploration platform is expected to encounter current of 3 m/s wave height 4 m and periods 15 seconds. A 1 in 20 scale modes is to be build and tested in hydraulic laboratory to determine the forces on the full scale structure.
(1) Explain and justify how you would scale the flow, determind current speed, wave height, wave period required for model.
(2) Force of magnitude 2.0 N is measured on an element of the modes, what would be the magnitude of coresponding forces on the full - scale strucutre.
The maximum vertical load and horizontal load have been identified and shown in the figure. Under this loading condition, you are asked to determine the horizontal deflection of joint C.
Design a riveted end plated Connection between a beam ISHB-300 and the flange of the Column ISHB-200 to transfer a vertical factored shear of 125 kN and a factored hogging bending moment of 125kNm.Use Shop rivets of 20mm dia.
The shape below has a cut along the entire length of the member thus making it an open section. The uniform thickness is 0.125in. Determine the maximum shear stress for the shape. Compare the stress for this open shape to a shape without a cut.
Determine the chemical oxygen demand (COD) of a mixture of 250 mg/l glutamic acid (C5H10N2O3) and 200 mg/l of glucose(C6H12O6).
A particular unit cell is cubic with ions of type A located at the corners and facecenters of the unit cell and ions of type B located at the midpoint of each edge of the cube and at the body centered position.
What will the freeway's density and level of service be before and after the ban? (Assume that the trucks are removed and all other traffic attributes are unchanged)
Plot the variation with depth (z) of the at-rest lateral earth pressure behind the wall, and determine the magnitude and location of the at-rest lateral earth force per unit length of wall.
A steel rod having a cross sectional area of 1/2in^2 and length of 600ft is suspended vertically. It supports a load of 5000 pounds at the lower end. If steel weighs 490 lb/ft^3 and E=30,000,000 psi, find the total elongation of the rod
A paddle wheel, inserted inserted into the volume, does 720 KJ of work on the air. If the volume is 2 cubic meters, calculate the entropy increase assuming constant specific heats.
The velocity along a pathline is given by V (m/s) = s^2 x t^(1/2) where s is in meters and t is in seconds. The radius of curvature is 0.5 m. Evaluate the acceleration along and normal to the path at s = 2m and t = 0.5 seconds.
the flow profile is such that u=u(max)*(1-(r/R)^2) where u is the flow speed and r is the distance from the centre of the pipe in the radial direction. What is the shear stress on the pipe wall What is the shear force exerted by the oil on a 1m lo..
Determine the normal depth in a trapezoidal channel with a bottom width of 6.4 ft and side slopes of 1 vertical to 2 horizontal. The discharge is 85 ft3/s. Manning's roughness factor is 0.025 and the channel bottom slope is 0.001
