The Reynolds number is a key parameter used to determine whether fluid flow will be laminar or turbulent. For fluid flow through a pipe, the Reynolds number is given by Re= (Vd)/v where Re is the Reynolds number (a dimensionless value), V is the velocity (m/s or ft/s) of the fluid, d is the diameter of the pipe (m or ft), and is the kinematic viscosity of the fluid (m/s² or ft/s). The kinematic viscosity, r, is a measure of the fluid's resistance to flow and stress. Except when at extremely high pressures, a liquid fluid's kinematic viscosity is dependent on temperature and is independent of pressure. The following chart lists the kinematic vis- cosity of water at three different temperatures: Temperature (°C) 5 D 20 50 T(°C) 5 Using this information, write a Python program that asks the user for the velocity of the water flowing through a pipe (V), for the pipe's diameter (d), and to select the water's tem- perature (1) from 5°C, 20 °C, and 50°C. Your program should then calculate the Reynolds number based on the input values. Test your program with the following data: Kinematic Viscosity (m/s) 1.52 x 10- 1.00 x 10-e 5.54 x 10-7 Input V(m/s) d(m) 3.5 0.001 20 50 0.9 Output Re 1.5 3.45 x 10 0.15 1.50 x 10² 0.02 3.25 x 10 Finally, format your program to match the sample below. Your output should exactly match the sample output, character for character, including all white space and punctuation. Hint: The string for printing" is "\u00e, which is the Unicode value for this symbol. Also note that the last line of output in each example broke across two lines because it was too long for the terminal. Your output should not include this line break. User input in the sample has been highlighted in Pappy's Purple to distinguish it from the program's output, but your user input does not need to be colored. Save your program as fluid mechanics_login.py, where login is your Purdue login. Then submit it along with a screenshot showing a run of all 3 test cases.
