Chapter 5.1, Problem 13E

To determine

The lower estimate and upper estimate for the total amount of oil that leaked out.

Expert Solution

The lower estimate for the total amount of oil leaked is 63.2L.

The upper estimate for the total amount of oil leaked is 70 L.

**Given:**

The function *r(t)* is an decreasing function.

The number of intervals is

Each interval value is

**Calculation:**

The distance approximation

The expression to find the lower estimate for the total amount of oil leaked

Here, for the time

Substitute 5 for *n* in Equation (1).

Substitute 7.6L/h for

Therefore, the lower estimate for the total amount of oil leakage from tank is 63.2 L.

The expression to find the upper estimate for the total amount of oil leaked

Here, for the time

Substitute 5 for *n* in Equation (3).

Substitute 8.7L/h for

Therefore, the upper estimate for the total amount of oil leakage from tank is 70 L*.*
