Concept explainers
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

- 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. Thank you!arrow_forwardPlease show your solution and at the same time BOX and SPECIFY the answers that corresponds to each blank on the question. Make sure to fill all the blanks. Thank you. STRICKLY FOLLOW THIS: Calculated Answers Express your answers without rounding off and without scientific notation unless instructed otherwise. Multiple Blanks Write powers or subscript as is. Ex: Use b2 if you mean b2 or b2 Spell out Greek letters. Ex: Use pi if you mean greek letter pi Write answers without spaces. Ex: Use 2epsilon0r3 if you mean 3e0r3 Write fractions with a slash. Ex: Use 1/2arrow_forwardPLEASE SHOW SOLUION STEP BY STEP WITH UNITS. PLEASE ANSWER IT IN 30 MINS. TOPIC: THERMODYNAMICS - PROCESSES OF GASESarrow_forward
- Completely solve and box the final answer. Please show the units to show the unit cancellations. Write legibly 7. A fire tube boiler develops 75 metric tons of steam at a pressure of 12.5 mpa and a temperature of 680°C for a period of 8 hours. The feedwater temperature is maintained at 95°C. If the boiler efficiency is 87.5%, find the average amount of coal burned in kg per hour if its heating value is 12,500 Kcal/kg.arrow_forwardPlease solve question 16-109 below this in the follwoing way: Please include a kinamatic diagram (one for velocity and one for acceleration). 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 (writing the x and y components of the equation and solving the equations for the unknowns). 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 16-109 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 :)arrow_forwardUsing graphical method solve this problem: Suppose you first walk A in a direction of B west of north then C in a direction D south of west. You rest for 20 minutes and started to compute the distance you traveled. Take A, B, C and D found in the table below. (You may use scale such as 1cm = 2m in your drawing) A. Sketch the problem in a Cartesian plane. B. How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position (resultant R)? C. What is the angle between AC ? D. What is the angle between your first walk A to the resultant R?arrow_forward
- Completely solve and box the final answer. Write legibly 7. Calculate the specific heat of a substance in BTU/lbm-ºR if 17.8 pounds can raise its temperature from 71.4 ºF to 118.5ºF in a period of 1.12 minutes. The computed amount of heat applied to it is 4.79 HP.arrow_forwardCompletely solve and box the final answer. Please show the units to show the unit cancellations. Write legibly 2. During a steady flow process, the pressure of the working substance drops from 1,380 kpa to 138 kpa, the speed increases from 61 m/s to 305 m/s, the internal energy of the open system decreases 58.1 KJ/kg, and the specific volume increases from 0.0625 m3/kg to 0.5 m3/kg. No heat is transferred, determine the work in KW if the mass flow at the rate of 272.15 kg/hr.arrow_forwardCompletely solve. WRITE LEGIBLY OR TYPEWRITE THE SOLUTIONS. BOX THE FINAL ANSWERS.
