Concept explainers
Whether the input pipe and each drainpipe are open or closed in specific subintervals of the 1 hour of time shown in the graph.

Explanation of Solution
Given information:
The intake pipe of a 100 gallon tank has a flow rate of 10 gallons per minute, and two drainpipes have flow rates of 5 gallons per minute each. The figure shows the volume
Calculation:
The intake pipe of a 100 gallon tank has a flow rate of 10 gallons per minute, and two drainpipes have flow rates of 5 gallons per minute each.
The below graph shows the volume
The combination of the input pipe and drain pipe in which the fluid is following in specific subintervals of the 1 hour of time shown on the graph is below;
Interval | Input pipe | Drain pipe 1 | Drain pipe 2 |
Open | Closed | Closed | |
Open | Open | Closed | |
Closed | Closed | Closed | |
Closed | Closed | Open | |
Open | Open | Open | |
Open | Closed | Open | |
Open | Open | Open | |
Open | Open | Closed |

- A 20 foot ladder rests on level ground; its head (top) is against a vertical wall. The bottom of the ladder begins by being 12 feet from the wall but begins moving away at the rate of 0.1 feet per second. At what rate is the top of the ladder slipping down the wall?
