Assignment 2
Question 1:
1) Figure 1 shows the command window results obtained from the data shown in Table 1.
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

(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
