You wish to fill a child's inflatable wading pool by using a garden hose. the hose you are using has an inside diameter of 3.0 cm and water travels though it at a speed of 1.5 m/s. if the pool is circular with an inside diameter of 3.1 m and you wish to fill it to a depth of 43 cm, determine the time (in minutes) required to fill the pool to this depth.

51.02 minutes

Explanation:

d = Diameter

r = Radius =

h = Height of pool = 0.43 cm

v = Speed of water = 1.5 m/s

A = Area =

Volume flow rate is given by

Volume of water needed is given by

Time taken is given by

The time taken to fill the pool is 51.02 minutes
