Heat and mass transfer are processes modelled by similar mathematical equations in the case of diffusion and convection. Through this **[course_title],** you will understand the balance between convection and diffusion that determines the total transport rates in chemical processes, as well as gives rise to many of the empirical correlations used in chemical engineering construction. Moreover, learn about the three fundamental modes of heat transfer that deals with the movement of heat and temperature grades.

**Assessment**

This course does not involve any written exams. Students need to answer 5 assignment questions to complete the course, the answers will be in the form of written work in pdf or word. Students can write the answers in their own time. Each answer needs to be 200 words (1 Page). Once the answers are submitted, the tutor will check and assess the work.
