14.5     What are the major pitfalls a supervisor can fall victim to when carrying out disciplinary functions?

14.6     What does it mean to be fair when disciplining employees?

14.7     Why should you know yourself and your employees well before attempting to discipline or punish them?

Write a program in MATLAB that processes a series of employees to determine the days until/since a given employee’s birthday as follows: To populate the employees' data, read in a comma separated file containing First Name, Last Name, Birthday Month, Birthday Day, and Salary. Use the file uploaded in Loud Cloud as an example. Build up an array of employee records (i.e., structures) where each record contains the employee's first name, last name, birthday (stored as an integer representing days from January 1st), and salary. Create a function that takes two numbers (month and day) as input and returns a single number (days since January 1st). This function will be used to "translate" the birthday format from that of the input file to that required for the data structures. 1. Create an array containing 12 values in which each number represents the days in each month of the year (i.e., 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31). 2. Subtract 1 from the input month and iterate over the array, adding in the value until you have the days in (month-1) months. 3. Add to this the number of the birthday day. Prompt the user to supply an employee’s first name. Using the result, search through the array of structures to find the requested employee. Display the number of days between the current date and the employee’s birthday. Note that this will be a negative number if the employee’s birthday has already passed.

Detailed methodology required in carry out experiment on the effect of adulterated gasoline (gasoline + kerosene) on the spark ignition engine.

6. An increase in roughness of a pipe with laminar flow would increase the pressure drop of the pipe. Assume the velocity is the same for the smooth pipe and the rough pipe.

a. True

b. False

A large vented tank containing water at 20 C has a pipe discharging to the atmosphere horizontally from the bottom. The pipe is 2.3 cm in diameter, has a surface roughness of 0.046mm, and is 40m long. The velocity in the pipe is 3.5 m/s. The flow in the pipe is turbulent. Neglecting minor losses, what is the water level in the tank above the centerline of the outlet pipe?

2.1 m

28.3 m

13.6 m

39.2 m

With the same setup (except water velocity), what is the maximum water height where the flow could be assumed laminar?

2.56 cm

4.1 m

1.1 m

6.3 m

2 kg/s of steam enters a turbine operating at steady state at 1 MPa, 200oC and exits at 40oC with a quality of 83%. Stray heat transfer and kinetic and potential energy effects are negligible. Determine (a) the power developed by the turbine, in kW, (b) the change in specific entropy from inlet to exit, in kJ/kg·K.

It is required to select a compressor for a car manufacturing plant which uses Pneumatic tools and equipment 24 hours a day continuously. Therefore, following tasks are required:
a. Research different compressors and select the most suitable compressor for such application.
b. Provide the diagrams, specifications and detailed information for the selected compressor.
c. Justify your selection with appropriate reasoning and comparisons.
d. Suggest alternative compressor type/s which could also be used for this application with justifications.

It is required to select a ‘chemical feed pump’ to transport corrosive chemicals such as potassium permanganate, ferric chloride and fluosilicic acid. Therefore, following tasks are required:
a) Research different pumps and select the most suitable pump for such application.
b) Provide the diagrams, specifications and detailed information for the selected pump.
c) Justify your selection with appropriate reasoning and comparisons.
d) Suggest alternative pump/s which could also be used for this application with justifications.

explain why constant volume combustion gives a higher indicated fuel conversion efficiency than constant pressure combustion for the same compression ratio.

Why is HTST better than LTLT? A juice product is needed to be heat processed to achieve 2 log reduction in microbial count. It could be accomplished by heating the juice product either at 65 or 75 C. The D value for bacteria cell death at 65 C is 10 S and z value is 10 C. D value for ascorbic acid degradation at 65 C is 50 s and Z value is 20 C. The heat transfer penetration data at 65 and 75 C is given below. Determine ascorbic acid losses at 65 C and 75 C
