SOLVE ALL THE NUMERICALS AND GIVE THE ANSWER

IF NEEDED MAKE APPROPRIATE ASSUMPTIONS AND STATE THAT.

$1.$ Calculate the power required by a shredder to operate for a throughput of $50\frac{t}{d}$ of MSW

having a work index of $450kW\frac{h}{t}on,$ considering the $80\%$ passing size of the feed and the

product as $25cm$ and $1cm,$ respectively.

$2.$ Determine the recovery and purity of metal and overflow in a screen$-$based process applied

to $150\frac{t}{h}$ of MSW with $12\%$ metals, given that the weight of underflow is $20\frac{t}{h}$ and the weight

of metals in the overflow is $1\mathrm{.}5\frac{t}{h}.$ Determine the overall efficiency of the screening process.

$3.$ What is the difference between a hauled container system and a stationary container system?

$4.$ Solid waste from a new industrial park is to be collected in large containers $($drop boxes$),$

some of which will be used in conjunction with stationary compactors. Based on traffic studies

at similar parks, it is estimated that the average time to drive from the garage to the first.

container and from the disposal site to the garage each day will be $15$ and $20$min, respectively.

The average time required to drive between two containers and collect waste is $8$min, the truck

makes $2$ trips a day, where the one$-$way distance to the disposal site is $25km($speed limit: $88$

$k\frac{m}{h}),$ and the average time spent to offload waste to the dispesal site is $20$ min. The crew is

given two $15-$min breaks per day. Determine the number of containers that can be emptied per

day, based on an $8-$hour workday.

$5.$ For the given waste stream:

a$.$ Determine the Moisture content of the waste stream?

b$.$ Determine wet and dry density of the waste stream?

c$.$ If $50\%$ of paper, and $100\%$ of cardboard and plastics are separated from the waste stream to

be recycled, how would this affect the moisture content and the wet and dry density
