Create the MATLAB® code for displaying pressure value demonstrated by different pressure sensor of a chemical plant unit as shown in Figure 1. Table 1: Pressure sensor vs Value (kPa) Pressure sensor 1 2 3 4 5 6 7 8 9 10 11 12 13 Value (kPa) 99 40 43 20 50 39 60 29 20 10 5 60 80 Figure 1: Results shown in command window (9 marks) Question 2: Consider that an acceptable temperature in between 200°C and 250°C for a distillation column. Write the MATLAB’s code using if command for the problem that specifies that the temperature of a distillation column shows • Temperature within specified range • The temperature has exceeded maximum value • The temperature is below the operating range (7 marks) Question 3 Consider a chemical company has a balance of money of $50k before closing down. The company plan to invest that amount of money in a third party company that generates a return of 8% annually. a) Write a MATLAB code using while loop to show how many years are needed to reach $1million. (6 marks) b) Using fplot code to plot money vs the number of years that reach $1million from $50k
