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?
a) 0.63 cm^3/g
b) 0.82 cm^3/g
c) 0.88 cm^3/g
d) 1.20 cm^3/g
A 4.00-cm-diameter, 0.80-m long rod of aluminum 7075-T6 is subjected to an axial tensile force with a factor of safety of 1.75. The yield stress and modulus of elasticity of aluminum 7075-T6 are 500. MPa and 210. GPa, respectively.
The smooth surface that provides the support at C lies in the y-z plane. Determine the reaction components that the ball and socket exert on rod ABC, the tension in cable BD, and force the smooth wall exerts on end C of rod ABC.
The concentration of cadmium ion (Cd^+2) in water is 225 mg/L. Will a precipiate be consumed or produced at pH 9.0? Will a precipitate be consumed or produced at pH 7.5
A particle travels along a straight line with a constant acceleration. When s=4ft, v=3ft/s and when s=10ft, v=8ft/s. Determine the velocity as a function of position.
Sketch and annotate the wedge described above.
Calculate the temperatures of the object with the indicated solar albedo and IR emissivity placed out in the sun where solar radiation is 1100 W/m^2. Assume a rectangular shape of length 4 m and width 3m.
You may pay $15,000 for an annuity that pays $2500 per year for the next 10 years . You want a real rate of return of 5% , and you estimated inflation will average 6% per year.
Your neighbor has the Bonda generator in the next problem and they have graciously extended a 100 foot extension cord to your home, which has a resistance of 0.0075 ohms per foot of wire (per lead). By how much is the delivered power reduced
A slurry containing 20 percent by weight of limestone (CaCO3) is processes to separate pure dry limestone from water. If feed rate is 2000kg/h, how much CaCO3 is produced per hour?
Suppose in 100 years energy consumption is still 330 Ej/yr, but coal supplies only 20 percent of total demand, natural gas supplies 30 percent, and oil 10 percent. The remaining 40 percent of demand is met by noncarbon-emitting sources.
A rectangular concrete channel is 3 m wide and 2 m high. The water 20 deg Celsius in the main channel is 1.5 m deep and is flowing at a rate of 30 m^3/s. determine the flow area, wetted perimeter, and hydraulic radius. Is the flow laminar or turbu..
Consider the flow of a gas between two parallel plates. If there were an increase in temperature due to heat transfer along the flow direction, the gas density would decrease. Assume the viscosity is unaffected.
