The level of water in a rectangular swimming pool needs to be lowered 4.00 inches. If the pool is 36.50 ft long and 15.00 ft wide, and the water is siphoned out at a rate of 5.0 gal/min, how long will the siphoning take?
1 ft^3 = 7.48 gal.

  • Chemistry -

    volum of water removed: 1/3 ft x 36.5ft x 15ft.

    calculate that volume

    Now convert ft^3 to gal. there are 7.48 gallons per ft^3

    Now,

    time=volumeinGallons/ratepump
