Textbook Question
Chapter 2, Problem 6P
The total world population in 2012 was about 7 billion, and Figure 2.11 shows that at that time the actual world population growth rate was about 1% per year. The figure also shows an anticipated roughly linear decrease in growth rate that extrapolates to zero growth in about the year 2080. Assuming an average growth rate of 0.5% between 2012 and 2080, what would the world population be in 2080? How does this compare with estimates discussed in the text for limits to human population?

List all of the parameters that you have used. The figures are attached belowarrow_forwardA simply supported beam for a building interior with 18 ft span has a cross section of 12 in width and 21 in overall depth. The beam is made with 5 ksi compressive strength concrete and 60 ksi reinforcing steel. The beam supports a uniform service superimposed dead load of 1.6 kip/ft, and a uniform service live load of 80 psf throughout the span. The beams are laterally spaced 20 ft apart c/c. Design this beam and show in a sketch.arrow_forwardThe dam presented below is 180 m long (in the direction perpendicular to the plane of the cross-section). For the water elevations given on the drawing: a) Construct the flow net (minimum number of equipotential lines should be 10), b) Calculate the rate of seepage for the entire dam, c) Find the total uplift force on the dam (ignore barriers), and d) Estimate the hydraulic gradient at points A, B, and D.
