Answer:

A factory uses a water tank to cool one of its pieces of machinery. To keep the water cold, fresh water enters the tank at a rate of 4 kilograms per second. Water also flows out of the tank at the same rate. The tank holds 8,000 kilograms of water.

The residence time for the average water molecule in that water tank is

2000

seconds.

2000 is correct

Answer 2

Answer:

2,000
