A city with 28,000 percent population is planning solid waste program. Population growth in the city is estimated to be 2.2% annually and the planning will designed for 30 years, The dumping area is located 20km away from the city. the trucks that carrying garbage has capacity of 8 cubs and each truck transport garbage twice per day. Solid waste generation 0.45kg/co pita/day.
A) Determine the amount of garbage produced in the city in each five years?
B) How much normal truck will be required to transport the garbage in each five years?
C) how many compactor trucks will needed to transport the garbage in each five years if the compacted percentage is 80%?
D) what will be the size of landfill after 30 years if the compacted garbage density will decrease to 75%?
E) what type of landfill can be applied for this type of waste if the city has topography and climate like new york city? F) what are you comments for the proposed solid waste planning in the city?
The cantilevered wild- flange steel beam is subjected to the concentrated force P at its end. Determine the largest magnitude of this force so that the bending stress developed at A does not exceed 180 MPa.
the flow profile is such that u=u(max)*(1-(r/R)^2) where u is the flow speed and r is the distance from the centre of the pipe in the radial direction. What is the shear stress on the pipe wall What is the shear force exerted by the oil on a 1m lo..
The water enters at 1 atm at 10 C and the flow rate through the turbine is 40 m3/s. The water is discharged from the turbine 200 m below the intake at 1 atm and the temperature of the water at the discharge is 10.2 C.
A rinsed and dried filter weighed 0.3588 grams before the sample was filtered and then weighed 0.3630 grams after the sample was filtered and being at dried at 103C. What is the TSS for this sample
a community has a current population of 2800. it is estimated that in 20 years its population will be 38000. the
The posItIon of a particle along a straight line is given by s = (t 3 - 9t 2 + 1St) ft, where t is in seconds. Determine its maximum acceleration and maximum velocity during the time interval 0 :5: t :5: 10 s.
The motor A delivers 3000 hp to the shaft at 1500 rev/min, of which 1000 hpis removed by gear B and 2000 hp is removed by gear C. Determine (a) the maximum shear stress in the shaft; and (b) the angle of twist of end D relative to end A.
Draw circle and put line with angle inside the circle that reflected in it. Make sure the measurement is punctual for each one. Angels required are 20-40-60 degrees. that means you have to draw three circles.
After the cone of depression has achieved equilibrium, the piezometric heads at two observation wells 40 and 95 m from the pumping well are measured as 78.9 and 83.4 above sea level, respectively.
The sulfur dioxide (SO2) stack-gas concentration from fossi-fuel combustion is 2 ppmv. Determine the stack-gas SO2 concentration in units of micro grams/m^3. Assume 0C and 1 atm pressure
An airplane flies at a speed of 360 mph at an altitude of 5000 ft. If the boundary layers on the wing surfaces behave as those on a flat plate, estimate the extent of laminar boundary layer flow along the wing in feet.
