Answer:
The kinetic energy correction factor the depends on the shape of the cross section of the pipe and the velocity distribution.
Explanation:
The kinetic energy correction factor take into account that the velocity distribution over the pipe cross section is not uniform. In that case, neither the pressure nor the temperature are involving and as we can notice, the velocity distribution depends only on the shape of the cross section.
The false statement about onStep is: B. The default number of steps per second is 30.
<h3>What is an onStep?</h3>
An onStep can be defined as a computerized telescope goto controller that is designed and developed to <u>animate shapes</u> while using it on a variety of mounting systems such as forks.
<h3>The characteristics of an onStep.</h3>
In Engineering, some of the characteristics that are associated with an onStep include the following:
- The onStep function can be called without user input.
- It can be used to animate shapes without user input.
- It only runs a certain number of times.
In conclusion, the default number of steps per second for onStep isn't 30.

Answer:
Explanation:
We know that Drag force
Where
is the drag force constant.
A is the projected area.
V is the velocity.
ρ is the density of fluid.
Form the above expression of drag force we can say that drag force depends on the area .So We should need to take care of correct are before finding drag force on body.
Example:
When we place our hand out of the window in a moving car ,we feel a force in the opposite direction and feel like some one trying to pull our hand .This pulling force is nothing but it is drag force.
