- The student is able to explain the basic physical concepts that are connected to heat flow, such as the heat capacity, the latent heat of melting and vaporization, and Newton’s law of cooling. The student can apply these concepts to solve heat flow problems.
- The student is able to explain the basic physical concepts of fluid flow and motion of objects in fluids; these concepts include Bernoulli’s law for fluid flow, and the buoyancy and drag forces on objects in fluids. The student can apply these concepts to solve problems concerning fluid flow and the motion of objects in fluids.
- The student can apply the concept of mathematical modelling to solve a real-life problem; this includes the identification of key variables, key assumptions, the relevant physical laws, and the formulation of the problem in terms of differential equations
- The student can reflect on the quality of the solution, by comparing with experimental data or observations, and relating this to the assumptions; on the basis of this, can draw conclusions and give suggestions for improvement in the modelling.

This course is an introduction to the physics of fluids and heat (Chapters 12 and 17 of University Physics by Young & Freeman. What is common between those two subjects is that for both there is the phenomena of flow, so it could also be viewed as an introduction into transport phenomena. The focus will not be on the fundamental principles, but rather on engineering applications, such as: ``what is electrical power that you can get from a reservoir lake?'', or ``what will be the final temperature of my lemonade when I add ice?''. While such problems appear simple, that is only so because a number of assumptions are made. In real life, hardly any engineering problem is simple: we just simplify it. In this course we want to create awareness of how much you have simplified a problem, and why (too complicated? effect negligible?). To this end, we will use the concept of a modelling cycle.
