Textbook Question
Chapter 16, Problem 1ICA
Which of the following are not valid MATLAB variable names? Circle all that apply. For those that are invalid, state why.
Expert Solution & Answer

To determine
Identify the valid MATLAB variables from the given variables and explain the reason for not valid variables.
Answer to Problem 1ICA
The valid and invalid MATLAB variables are identified and explained the reason for invalid MATLAB variables.
Explanation of Solution
Description:
- a. BigNum.docx: The MATLAB variable BigNum.docx is invalid variable since it contains the special character “.”.
- b. Six_Vals: The MATLAB variable Six_Vals is a valid variable since it obeys the naming rules of the MATLAB.
- c. This is a very long MATLAB variable name: As the variable contain the space, the MATLAB variable is not a valid one.
- d. 2BR02B: The variable cannot begin with the number. As the variable begins with the number 2, the variable 2BR02B is an invalid one.
- e. Is_This_Valid?: As the variable contains the special character “?”, the variable is an invalid variable.
- f. Rocket=Space+100;: As the variable contains the special characters “=”, and “;”, the variable is an invalid variable.
- g. Mult2: The variable is a valid one.
- h. log: As the variable log is a name of common function, the variable is an invalid variable.
- i. GClefSign: The MATLAB variable GClefSign is a valid one.
- j. AbcDEFGHijKLmnopqrstuvWXyz_Has_Lots_of_Characters: The variable is a valid one.
- k. DoNotPassGo_DoNotCollect$200: As the variable contains the special character “$”, the variable is an invalid variable.
Conclusion:
Thus, the valid and invalid MATLAB variables are identified and explained the reason for invalid MATLAB variables.

Q2: (15 Marks)
A water-LiBr vapor absorption system incorporates a heat exchanger as shown in
the figure. The temperatures of the evaporator, the absorber, the condenser, and the
generator are 10°C, 25°C, 40°C, and 100°C respectively. The strong liquid leaving
the pump is heated to 50°C in the heat exchanger. The refrigerant flow rate through
the condenser is 0.12 kg/s. Calculate (i) the heat rejected in the absorber, and (ii) the
COP of the cycle.
