The density of atmospheric air varies with elevation, decreasing with increasing altitude.
(a) Using the data given in the table, obtain a relation for the variation of density with elevation, and calculate the density at an elevation of 7000 m.
(b) Calculate the mass of the atmosphere using the correlation you obtained. Assume the earth to be a perfect sphere with a radius of 6377 km, and take the thickness of the atmosphere to be 25 km.

A sample of clay was obtained from a point below the water table. An oven-drying test performed on this sample resulted in the following data: Mass of can= 10.88 g Mass of can + wet soil = 116.02 g
Set up life cycle diagram for both alternatives and calculate net present value (NPT) and annual cost for the life time.
A soil specimen has a water content of 18% and a wet until weight of 118.5 lb/ft. The specific gravity of solids is found to be 2.72. Find the dry unit weight, void ratio, and degree of saturation.
You should provide the structural engineer with a formal typed report that will include all of your analyses and final size of the footing. You should also include all of your design assumptions in your report.
An engineer is considering the development of a small wind turbine(D=1.25m) for home applications.The design wind speed is 15mph at T=10 degree celsus and p=0.9 bar.The efficiency of the turbine is n=20%,meaning that 20% of the kinetic energy in the ..
