Question

In a leaky bucket used to control liquid flow, how many gallons of liquid are left in the bucket if the output rate is 5 gal/min, there is an input burst of 100 gal/min for 12 s, and there is no input for 48 s?

Answer 1

The input is 100 gal/min, will be 100/60 = 1.667 gal/sec and 1.667*12 =20 gal in 12 seconds.

The output is 5 gal/min, will be 5/60 = 0.08333 gal/sec

As input continues for 12 seconds, 0.8333 * 12 = 1 gallon will be loss in 12s and 0.8333*48 =4 gallon in 48 second.

1+5 gallon in 1 minute and the remaining liquid will be 20-5= 15 gallons after 1 minute.
