Textbook Question
Chapter 18, Problem 12RQ
Create a program to determine whether a given Mach number is subsonic, transonic, supersonic, or hypersonic. Assume the user will enter the speed of the object in meters per second, and the program will determine the Mach number (actual speed divided by the speed of sound). As output, the program will display the Mach number to two decimal places. The program should include a check to ensure that the user entered a positive value. If a nonpositive value is entered, the program should inform the user of the error and terminate.
The speed of sound 1s about 343 m/s. The classifications are as follows:
Subsonic < Mach 1
Transonic = Mach 1
Mach 1 <Supersonic< Mach 5
Hypersonic ≥ Mach 5

On an alien planet, the law that expresses the flow of blood through a blood vessel, F, as a function of the radius r of the vessel is
f=kr5/2where k is a constant.
Certain geological features of this planet produce a gas that changes the radius of blood vessels by 5% at the time of inhalation. What would the corresponding increase in blood flow through the vessel at this time be?
Write 1-2 sentences explaining how you found your answer.
Please include a kinamatic diagram (for velocity)
Please DO NOT solve this using velocity analysis (cartesian vector analysis). I would like it to be solved using scalar method. We dont use 3D in this course. We only use scalar analysis for the relative velocity equation as requested in the question (writing the x and y components of the equation and solving the equations for the unknowns). Below I have attached a sample question with solution in order to get an idea on how to use the scalar method to solve my question. I would like question this to be solved in a similar way. Thank you for your understanding.
If you can solve it as soon as possible that would be great and I will give you a thumps up and positive feedback :)

In Rizal province, one of its power plants has been thoroughly monitored for possible conversion into a wind power plant. A propeller wind turbine is to be used. Survey showed that Rizal Province at a height of 10 meters above the ground has a minimum wind speed of 7.1 miles per hour duringthe month of June and a maximum wind speed of 12.9 miles per hour during the month of January. The minimum temperature is at 75 degree Fahrenheit during the month of January and maximum temperature is at 89 degree Fahrenheit during the month of May. The existing power plant has an output of 54MW. For the proposed wind power, the power coefficient of turbine is 35% and the generator efficiency is 95%. Theimpeller diameter is assumed not to exceed 90m. Determine the following:a. Theoretical Wind Power Outputb. Electrical Power Outputc. Number of turbines to be installed

- Hi. I am trying to practice this problem using a checker online, but everytime I recalculate my answer it always says it's incorrect. So far I have calculated and tried to input the following values: 1 hp, 1.01 hp, and 0.8 hp but it always keeps saying they are incorrect. Am I missing a sign change? (Should the answer be negative?) Or am I solving this incorrectly and getting the wrong value each time? Please help show me the correct steps on how to get the correct answer as I am trying to learn this process.
