The United States Environmental Protection Agency (EPA) has published the following data for municipal solid waste generation (in millions of tons).
Year: 1960 1965 1970 1975 1980 1985 1990 1995 2000
MSW: 88 104 121 128 152 166 205 221 249
a) Assume that the growth is exponential (i.e., plot the log of generation versus time) and calculate a value for the annual growth rate (% / yr).
b) If the annual rate of population growth is 1.8%, calculate a value of the annual rate of growth in per capita generation of solid waste.
c) Estimate a value of MSW generation in the year 2025.
d) Suggest one method that might be used to decrease the rate of growth in per capita generation rate
what is the difference between normal stress and allowable shear stress. What is the difference between axial and hoop stress and how do you calculate tensile force per mm.
An engineer is to design a channel lined with planed wood to carry 2 m3/s of water on a given slope. The channel cross section can be either a 90 degree triangle or a square. Which would require less wood and by what percentage
A drilling engineer wishes to support pipes of length L on blocks so that the magnitude of the bending moment in the pipes directly over the supports is equal to the magnitude of the bending moment at the center of the pipes.
At the instant, the system is at rest and the spring is compressed by 50mm. Determine A) Velocity of block A when the spring is unstretched B) Maximum velocity of Block B C) Maximum deflection in the spring
a belt sander is being brought up to operating speed at the instant of the belt is rotating in the clockwise direction ar 4 ft/s and acceleration at 40 ft/s. the tensioning cylinders A and B have a radius of 2.5 in.
A watershed has four sub-areas. The annual precipitation and evaporation from each of the sub-areas are given in Table(below). Assume that there is no change in groundwater storage on an annual basis and calculate for the whole catchment the value..
Determine the rate at which heat is added in the boiler, the power required to operate the pumps, the net power produced by the cycle, and the thermal efficiency.
The total dissolved inorganic carbon (TIC) of a sample of groundwater is 8.33 mM. The temperature of the aquifer is 15C, the pH is 7.5, and the ionic strength is 0.05 M. What is the H2CO3, HCO3-, CO3 2-, and the partial pressure of CO2? [Use activ..
Plot the variation with depth (z) of the at-rest lateral earth pressure behind the wall, and determine the magnitude and location of the at-rest lateral earth force per unit length of wall.
if a pipeline is horizontal, what is the porportion of the potential energy head at the upstream crossection that is changed to kinetic energy head at the downstream crossesction
A Ferris wheel with a radius of 35 feet starts from rest and undergoes an angular acceleration of 0.05 rad/s^2. Compute the magnitude of the velocity and acceleration vectors at 5 seconds for a point on the rim of the Ferris wheel.
An object is held in the air 30m above ground and released. Assume the drag force due to air resistance is given by Fd = 1.0Vy. What is the mass of the object necessary so that it reaches ground in 3s
