There are several equations of state available. The Redlich-Kwong equation of state is given by P = RT/v - b - a/v(v + b) Squareroot T where R is the universal gas constant, T is the absolute temperature (K), P is the absolute pressure (kPa), and v is the volume of a kilogram of gas (m^3/kg). The parameters a and b are calculated by: a = 0.427 R^2T_c^2.5/P_c b = 0.0866 T_c/P_c where P_c = 4600 kPa and T_c = 191 K. As a chemical engineer, you are asked to determine the amount of methane fuel that can be held in a 3-m^3 tank at a temperature of -40 degree C with a pressure of 65,000 kPa. Use an open locating method of your choice to calculate v and then determine the mass of methane contained in the tank. Use a tolerance limit of 0.00001% absolute error. Create a SCILAB program that will calculate v and the mass of methane contained in the tank.

1. Your professor is dealing with a case where a student was alleged to have cheated on the final exam. Would documentation be important? If so, what type of documentation would be necessary? (Worth 5 marks)

A bicycle generator is a form of green energy and a good way to work out Simulate a bicycle generator on Simulink using simscape to find the output current and voltage that can be produced from pedaling. 1.Bicycle 5.Light bulb 3. Drive Belt 2. Stand 4. Motor Notice that there is a unidirectional clutch between the pedal and the main gear in the bicycle Maximum human force is 30 N Assume any needed dimensions and data.

Problem 2 The Bell-LaPadula rules for MLS concern reads and writes to files. Each file F has a classification, which is a label L(F), each subject S has a classification, which is a label L(S); and there is an ordering "c=" on labels. This ordering is the basis for the "no read up" and "no write down" rules that define read and write operations authorized for a subject. The usual accounts of Bell-LaPadula are silent about the response generated when a read or write operation would violate the BLP access rules. For this assignment, assume that such an access attempt returns an error message "Access Denied: File unavailable". And assume that an attempt to access a file that does not exist returns the same message. a. Suppose we wish to support an additional operation b. createFile(FName, Lbl ) whose execution creates a new empty file that is named FName and has label Lbi. What, if any, rules about labels should be imposed on execution of createFile if we want to ensure that classified information doesn't leak C. Suggest error messages to be returned from invoking the createFile for the following two cases: i. the rule you suggest in (a) is not satisfied. ii. the rule you suggest in (a) is satisfied but a file with name FName already exists. Give a rationale for the wordings you propose
