AI Thread Summary
In a PV graph, a reversible process follows a smooth, continuous curve, while an irreversible process is represented by two distinct paths. The irreversible process typically shows a vertical drop followed by a horizontal movement to the final state. This difference highlights the efficiency and characteristics of each process in thermodynamics. Understanding these distinctions is crucial for analyzing energy transformations. The discussion emphasizes the importance of accurately representing these processes in PV diagrams.

What's the difference in the PV graph for a reversible process vs. an irreversible process?

I know for adiabtic you would get a smooth (log like) downwards cruve if it's reversible but what about ireeversible?

Thanks

I'm pretty sure a reversible process travels along the same curve while the irreversible process will have 2 separate paths.

check out wikipediea http://en.wikipedia.org/wiki/Reversible_process_(thermodynamics ) it could be useful.

Which p do you want to use in your pV diagram in case of an irreversible process?
 
thanks I think I got it. Its just I straight vertical line down then across to where the final pt is suppose to be

cheers :D

Thread 'Gauss' law seems to imply instantaneous electric field propagation'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'A scenario of non-uniform circular motion'

(All the needed diagrams are posted below) My friend came up with the following scenario. Imagine a fixed point and a perfectly rigid rod of a certain length extending radially outwards from this fixed point(it is attached to the fixed point). To the free end of the fixed rod, an object is present and it is capable of changing it's speed(by thruster say or any convenient method. And ignore any resistance). It starts with a certain speed but say it's speed continuously increases as it goes...

Thread 'Do electron density waves accompany EM waves in coaxial cables?'

Maxwell’s equations imply the following wave equation for the electric field $$\nabla^2\mathbf{E}-\frac{1}{c^2}\frac{\partial^2\mathbf{E}}{\partial t^2} = \frac{1}{\varepsilon_0}\nabla\rho+\mu_0\frac{\partial\mathbf J}{\partial t}.\tag{1}$$ I wonder if eqn.##(1)## can be split into the following transverse part $$\nabla^2\mathbf{E}_T-\frac{1}{c^2}\frac{\partial^2\mathbf{E}_T}{\partial t^2} = \mu_0\frac{\partial\mathbf{J}_T}{\partial t}\tag{2}$$ and longitudinal part...
