- Simplify this statement:
- The continuity equation in fluid dynamics for steady fluid flow through a stream tube equates the product of the density, velocity, and area at two points that have varying cross-sectional areas. For incompressible flow, the densities are constant so the equation is A1V1 = A2V2 . If the areas and V1 are known, V2 can be found as . Therefore, whether the velocity at the second point increases or decreases depends on the areas at the two points. Write a script that will prompt the user for the two areas in square feet, and will print whether the velocity at the second point will increase, decrease, or remain the same as at the first point.
- Rewrite the following nested if-else statement as a switch statement that accomplishes exactly the same thing. Assume that num is an integer variable that has been initialized, and that there are functions f1, f2, f3, and f4. Do not use any if or if-else statements in the actions in the switch statement, only calls to the four functions.
- Whether a storm is a tropical depression, tropical storm, or hurricane is determined by the average sustained wind speed. In miles per hour, a storm is a tropical depression if the winds are less than 38 mph. It is a tropical storm if the winds are between 39 and 73 mph, and it is a hurricane if the wind speeds are >= 74 mph. Write a script that will prompt the user for the wind speed of the storm, and will print which type of storm it is.
if number > 100
number = 100;
else
number = number;
