Indefinite Integrals

The water inflow rate into a storage tank is not constant but increases over time. Initially, the pump delivers water at a rate of 5 L/min. However, the inflow rate increases by 2 L/min for each additional minute due to rising pressure or system adjustments. This scenario can be described mathematically by a linear function:

Water flows into a large industrial storage tank, but the inflow rate is not constant. Initially, the pump delivers water at 5 m³/s.

The water inflow is increasing at a constant rate of two cubic meters per second due to continuous system adjustments.

This steady change makes the water inflow rate a linear function of time...
