It is desired to convert from slow sand filters to high-rate filters. The slow sand filters operate at a rate of 10 million gallons/acre-day and have a total area of 15 acres. Assuming the high-rate filters are rated for 6 gpm/ft2, and each filter has an area of 1,000 ft2, how many filters are required

Total 17 high rate filters are required

Step-by-step explanation:

Given -

Rate of filtration of slow sand filters = 10 million gallons/acre-day

Total million gallons of water filtered per day = 10 million gallons/acre-day * 15 acres

= 150 Million gallons per day

Rate of filtration of high rate filters = 6 gpm/ft2

Area of one high rate filter = 1,000 ft2

Volume of water filtered by 1 high rate filter is 6 gpm/ft2 *1,000 ft2 = 6000 gallons per minute  = 8640000 gallon per day

Number of filters required = 150 million gallons per day /8640000 gallon per day

150 * 10^6/8640000

17

Total 17 high rate filters are required

i dont know

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
