I was in a situation similar to this one in real life: having to adjust the salt level in a pool.
In metric:
The pool is 8*4 m long and 2m deep on average, the current salt level is 2g/l and the salt comes in 20kg bags.
How many bags of salts do I need to pour in the pool to adjust the salt level to at least 3g/l ?
Answer:
! The pool contains 8m4m2m= 64m³ or 64000l of water, I need an extra 1g/l of salt per litres so 64000l*1g/l = 64000g or 64 kg. So with 4 bags I’ll have enough salt.
In imperial:
The pool is 20*10ft long and 5ft deep on average, the current salt level is 2000ppm and the salt comes in 40lbs bags.
How many bags of salts do I need to pour in the pool to adjust the salt level to at least 3000ppm?
Answer:
! I’m just gonna drive to the store with my truck to pick up 2 bags at the time and see if it’s enough, no way I’m doing the calculation.
