1.One of the last major offshore construction activities is to set the production topsides onto the floating Spar. If the Spar is 140 feet in diameter, how much will it sink down as a 12000 ton topsides deck is set?
2.What is the weight of a 20 ft diameter hollow sphere with 1 ft thick walls (Assume concrete weighs 4000 lbs/yard)?
3.Here is the problem:When measuring a distance AB, the first taping pin was placed 1.5ft to the right of line AB and the second pin was set 1.5 ft left of line AB. The recorded distance was 236.89 ft. ( Assume 3 taped segments, the first two 100 ft each.)Calculate the corrected distance.
4.100g of water are mixed with 150g of another fluid (density = 790 kg/m3 ). What is the specific volume of the mixture, assuming that the volumes are additive and the mixture is homogeneous?

b) 0.82 cm^3/g
c) 0.88 cm^3/g
d) 1.20 cm^3/g
A pump is necessary to lift water from the clear well (reservoir) at a water treatment plant to a storage tower 50-ft high and some distance away. A flow rate of 15 cubic per second (cfs) is required (68F).
he project duration is planned for 20 weeks. The project budget is $40,000 and is planned to be spent on a level bases through out the project. You are at the end of week 10, the accounting department tells you the project has spent $19,500
The coefficient of volume compressibility is 4x10-4 m2/kN at the ground surface and the reduction in the coefficient of volume compressibility with depth equals depth*0.1*10-4 m2/kN.
Should Bernard bid for the project assignment? Why or why not? Does Bernard have an unfair advantage over firms having designed the project on which he wants to bid?
