Here I introduce the concept of the heat engine. I define the source and the sink. I then use the first and second laws of thermodynamics to derive the Carnot efficiency. I then point out that the…

Here I go through the two examples of a throttle and a heat exchanger. I look at the energy equation, and solve that. THen I look at the rate of entropy production. It is positive in both cases…

Here I describe what is hapenning in the two videos of the kid falling off the bike and the kid falling off the bike in reverse. I describe the natural order of things beign that order decreases and…

Here I show a series of irreversible processes. I discuss how in each case high quality energy is converted into lower quality energy and that this is inevitable. I introduce the concept of entropy.

Here I introduce the course, and inform student how they should be studying. I show the week by week plan . Then I go through the syllabus and pick up some of the fundamental concepts I will be…

From corporate to human rights, find out more about the different types of law you could work within, with speakers from Freeths, DLA Piper and Addleshaw Goddard LLP.

Law alumnus Ian Bagshaw (LLB Law 1993), a partner with White & Case, kindly gave a talk and answered questions from students about the impact of the COVID-19 pandemic on city law firms and their…

Here I introduce the T-s diagram for ideal gasses. I show that an isentropic expansion is a vertical upward line on this and an isentropic compression is a vertical downward line. I then show that in…

I introduce heat exchangers. Then I look at the heat transfer in them from the point of the first law of Thermodynamics. I then explain the irreversibility in a heat exchanger in terms of entropy. I…

Here I derive the steady flow energy equation for thermal systems. I show how it can be used for calculating the work in an adiabatic process using the gas laws.

Here I show that the polytropic process is a good way of describing changes in condition for closed systems with ideal gasses. I look at different values of the exponent, n. Then I calculate some at…

What is a closed system. The first law for closed systems. Definition of adiabatic and isentropic processes.

Here I introduce the first law of thermodynamics by thinking about the types of energy that we will deal with. I then shpow that these are interchangeable. Finally, I deduce the energy equation.

We were delighted to welcome Lord Burnett of Maldon, the Lord Chief Justice of England and Wales to the University on Tuesday 5 March. The Lord Chief Justice’s lecture on ‘Rethinking our…
