water needs to be removed from an underground chamber before work can commence. when the water was at a depth of 3m five suction pipes were used and emptied the chamber in 4 hours. if the water is now at a dpeth of 5 m and you want to empty the chamber in 10 hours time how many pipes need to be used

Sagot :

Answer:

8 pipes

Step-by-step explanation:

given that when height increases also time increases and automatically no of pipes will be decreased Mathematically;

h∝t•1/p

remove proportionality symbol and we will get

h=kt

p

make k as subject and we'll get

k=hp

t

find the value ok k

k=3×5

4

k=15

4

k=3.75

from h=kt. make p as subject and the answer should be

p=kt. find p

h

p=3.75×10

5

p=37.5

5

p=7.5 or 8

hence 8 pipes should be used
