PHYSICAL PROBLEMS OF INTEGRATION
Chemical Engineering: What is time required
for oxygen to be consumed in the fuel cell?
One of the
problems affecting the performance and hence commercialization of the
direct methanol fuel cell (DMFC) is the depolarization of the oxygen
reduction electrode caused by methanol crossover. In an attempt to
understand the mechanism of the depolarization process, an
electrokinetic model for mixed oxygenmethanol current on platinum
requires
integration of a function.

Civil Engineering: In a class X528 wells, you need to use
integration to find if the concentration of benzene is below the
toxicity level at a certain distance from the point of contamination.

Electrical Engineering:
All electrical
components, especially offtheshelf components do not match their
nominal value. Variations in materials and manufacturing as well as
operating conditions can affect their value. Suppose a circuit is
designed such that it requires a specific component value, how confident
can we be that the variation in the component value will result in
acceptable circuit behavior? To solve this problem a probability density
function will need to be
integrated to determine the confidence interval.

General Engineering: The upward velocity of a rocket is given
as a function of time. To find the distance covered by the rocket from
lift off requires integration.

Industrial Engineering: Are there as many tissues as advertised in the toilet paper roll? To
find the probability of the number of tissues to be less than
advertised, one needs to use
integrate a function.

To find how much a steel shaft will contract so that it can be shrink
fit into a hollow hub, we need to use
