Chapter 7 ENTROPY
... Assumptions 1 This is a steady-flow process since there is no change with time. 2 Kinetic and potential energy changes are negligible. 3 Air is an ideal gas. 4 The process involves no internal irreversibilities such as friction, and thus it is an isothermal, internally reversible process. Properties ...

Chapter 5 Diffusion Availability
... The availability is the maximum work that can be extracted from the substance as it undergoes a reversible process from a given state to the environmental state. When a substance is in the environmental state, it is in thermal and mechanical equilibrium with the environment and therefore has no work ...

... power that is actually converted into usable heat. This is e.g. the heat transferred into the (liquid) coolant and can be calculated as follows: Precovered heat = V̇ · cp · ∆T · ρ Coolant parameters are: Volume flow V̇ , heat capacity cp , temperature increase ∆T and density ρ. Due to technical issu ...

Statistical and Low Temperature Physics (PHYS393)
... starting field of Bi = 8 T, and a starting temperature of Ti = 10 mK. This is just to reduce the entropy by 9%. From the earlier explanation on the principle of magnetic cooling, we know that an lower entropy means that a lower temperature can be reached during demagnetisation. It also means a highe ...

Abstraction and its Limits: Finding Space For Novel Explanation
... that there is a sense in which fundamental theories may be regarded as explanatorily inadequate. In this paper, I also want to go a step beyond merely noting the importance of abstraction for explanation (although my account will differ significantly from Batterman’s). I will examine the possibility ...

Melting ice with salt - a thermodynamic model - Til Daim
... Experimentally part of this study has been performed in order to verify the outcome of the model. Five solutions with different salt concentrations (5, 10, 15, 20 and 23 w%) have been experimentally tested to determine the temperature change inside the reactor caused by adding of a certain amount of ...
