Derive a relation between velocity in rad ial direction v(r) and centerline velocity vc for a fully developed laminar flow inside a horizontal pipe with a head loss h1 for a pipe length L.

A trapezoidal channel is to be designed through a silty clay alluvium on a slope of 0.0035 ft/ft. The angle of repose of the material is 35° and the Manning coefficient is 0.025. If the channel is to be designed to carry a maximum discharge of 700 cfs at a depth of 4.9 ft, determine if rip-rap will be required, and, if so, compute the stone size for both the bed and sides.

1. The Incineration becomes a key role to end up with a huge decrease of MSW volume. But in Oman, there are not many of them to be find comparing to the European Union. Discuss some reasons and point out the pros and cons of Incineration in economics, security as well as social and environmental impacts. Head them into a discussion.

1) Select the lightest section to support a axial load (DL=700 kips y LL= 300 kips). The
element is braced, so LX= 22 ft and LY= 12 ft. The end support conditions are:
a) (Fixed/pinned) and it is specified to use A572 gr. 60. (verify slenderness and
local buckling)
b) (Fixed/Fixed) and you must use A-36

You are part of the water supply engineering team of your council. Your team is working on a certain part of cast iron piping of a water distribution system involving a parallel section. Both parallel pipes have a diameter of 30 cm, and the flow is fully turbulent. One of the branches (pipe A) is 1000 m long while the other branch (pipe B) is 3000 m long. If the flow rate through pipe A is 0.4 m³/s, determine the flow rate through pipe B and the head loss in pipe B. Disregard minor losses. Consider the water temperature to be 15°C. Assume that the flow is fully turbulent (i.e. the friction factor is independent of Reynolds number).

A rock is thrown with an initial velocity of 30 m/s at an angle of 60° above the horizontal from a height of 1.5 m toward a cliff. After 4 seconds, the rock lands on the top edge of the cliff.

(a) Calculate the height of the cliff.

(b) Calculate the maximum height reached by the rock along its trajectory

(c) Determine the speed of the rock just before hitting the cliff.

a)Describe how observing two satellites from two receivers can allow clock errors

to be removed.

b). Describe how ionospheric effects may be removed from GPS signals

Find the weight (in kg) of cement, water, flyash, fine and coarse aggregate to produce a cement/flyash mix for pumped concrete, using the British Method that has a characteristic 28-day compressive strength of 45 MPa. One hundred laboratory test results on the controlling mix show a standard deviation of 5.3 MPa (k=1.65). The exposure classification for durability purposes is A2 and the conditions require a fly ash/ high early strength cement blend (with a 40% proportion of fly ash). The specific gravity of the crushed coarse 20 mm aggregate to be used is 2850 kg/m³ and its dry rodded density is 1600 kg/m³. The specific gravity of fine aggregate is 2750 kg/m³ and its fineness modulus is 2.5. Assume the high early strength cement density is 3150 kg/m³ and fly ash density to be 2000 kg/m³

You are part of a Design and Construct team for a conference centre and 300 bed hotel accommodation in Darwin, Northern Territory. The site is 10 hectares on the oceanfront. The developer wants the project to be environmentally friendly and to minimise energy consumption and water usage while maintaining a luxury hotel feel. List the factors and strategies that you would consider most important in the design of this building, i.e. the design adaptations for the building.
