BAE 310 Heat and Mass Transfer in Biosystems Engineering (3.0 Credit Hours)
Course Description: Fundamental principles of steady state and transient heat and mass transfer in biosystems engineering. Heat transfer will include conduction, convection, and radiation. Mass transfer will include liquid-gas, solid-gas, and solid-liquid equilibrium scenarios, as well as convective, diffusive, and osmotic mass transfer. Governing equations and boundary conditions for both heat and mass transfer will be included with special attention to industrial, biological, and bioenvironmental problems.
Prerequisites: MA 214 and ME 220; concurrently CE 341
Student Learning Outcomes: At the end of this class a successful student will be able to:
1. apply engineering fundamentals and governing equations for analysis and solution of conduction, convection, and radiation heat transfer problems.
2. describe physical mechanisms underlying heat and mass transfer processes and the relevance of these processes to industrial, biological, and bioenvironmental problems.
3. relate each term in heat and mass equations and types of boundary conditions required for solution to biosystems engineering problems.
4. describe the various components needed for setting up conservation of mass for a single species.
5. apply engineering fundamentals and governing equations for analysis and solution of diffusion and convective mass transfer problems.

Grading: Grades will be rounded to the nearest integer and assigned as follows:
A = 90% or above, B = 80%-89%, C = 70%-79%, D = 60%-69%, and E = 59% or below
Reading Assignments: Lectures will supplement the reading material from the textbook; not necessarily repeat the material. Therefore, it is imperative that you read the textbook before class in order to understand the material.
Exam Format: All exams will be open-book take-home exams unless further noticed. You will need to return the paper within set time limits (4 hours for midterms and 8 hours for final). You are encouraged to prepare your cheat-sheets. A pack of equations and charts will be supplied to you.
Mid-term Grades: Mid-term grades will be posted in myUK by the deadline established in the Academic Calendar (http://www.uky.edu/Registrar/AcademicCalendar.htm).
Final Exam: The final exam will be given during finals week at the time determined by the UK finals exam schedule in the regular meeting room (http://www.uky.edu/registrar/calendar).
Submission of Assignments: All homework assignments should be turned in online. It is preferred to write the answers on an engineering paper or electronic format. Assignments are due at the beginning of the lecture period on the due date, unless otherwise specifically denoted on the assignment or announced to the class. Homework will typically be assigned on a weekly basis and due on Mondays.
In-Class Assignments: In-class assignments are due at the end of the lecture period on the due date, unless otherwise specifically denoted on the assignment or announced to the class.
