Design the total landfill area requeremoent for the haramaya town. Assume the total population of the haramaya town is 120000 per capita soled waste generation 10kg/day
and (b) recycling rate is 20% of total waste generation and (c) average depth of landfill is 45m. (d) percent reduction of waste 25% and (e) Cv=1.21. If the design life of the
Haramaya town landfill is 30 years and population growth rate is 2.15%, what is the
required area and volume of the landfill?​

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
