Question

You have an outdoor swimming pool that is 5.0 m wide and 12.0 m long. If weekly evaporation is 2.35 in, how many gallons of water must be added to the pool each week (if it doesn't rain)?

Answer 1

Water should be greater than 946.11 gallons per week to prevent the pool from drying.

Explanation:

You have an outdoor swimming pool that is 5.0 m wide and 12.0 m long.

The height of water evaporated is = 2.35 inch

We will convert this to m.

1 inch = 0.0254 meter

So, 2.35 inch =
`2.35*0.0254=0.05969` meter

Now, volume of water in the pool =
`5*12*0.05969=3.5814` cubic meter per week.

1 cubic meter = 264.172 gallons

So, 3.5814 cubic meter =
`3.5814*264.172=946.11`gallons

Hence, the volume of the water that should be poured in the swimming pool should be greater than 946.11 gallons per week to prevent the pool from drying.
