Chestermiller's latest activity
-
Chestermiller replied to the thread Spring aproximation.Yes, neglecting dissipation factors such as air drag. -
Chestermiller replied to the thread Undergrad Is Callen right in claiming dQ=TdS for all quasi-static processes?.A quasi-static path is considered to represent a continuous sequence of thermodynamic equilibrium states. -
Chestermiller replied to the thread Undergrad Joule-Thomson Expansion.Who says that in thermodynamics, we study gases that are in thermodynamics equilibrium? The states of the gas in irreversible processes... -
Chestermiller reacted to Andrew Mason's post in the thread Undergrad Is Callen right in claiming dQ=TdS for all quasi-static processes? with

$$\Delta S=\int dS=\int dQ/T$$ is the definition of change in entropy, where dQ is the infinitesimal heat flow over a reversible path... -
Chestermiller replied to the thread Old man, new member.Was it also called the Missouri School of Mines, or is that something different? -
Chestermiller replied to the thread Graduate Strain Tensor Based on Clifford Algebra.For large deformations, the definition of the strain tensor is not unique. There are many tensorial forms at large deformation that... -
Chestermiller replied to the thread Rubber tyre “melting” inside, turned to deadly goo. Why?.Thermal chemical decomposition of the rubber. -
Chestermiller replied to the thread High School Internal energy and gravitation.The more general form of the 1st law of thermodynamics is $$\Delta U+\Delta (PE)+\Delta (KE)=Q-W$$where PE is the gravitational... -
Chestermiller replied to the thread Pressure-Volume Work.At any point during the process, the pressure P is related to the mass m by $$PA=mg$$or $$m=\frac{PA}{g}$$Therefore, mass can be used as... -
Chestermiller replied to the thread Pressure-Volume Work.The total work is path independent, but the path for adiabatic reversible is different from the path for isothermal reversible, and the... -
Chestermiller replied to the thread Pressure-Volume Work.Initial pressure = ##P_0A=m_0g##, where ##m_0## is the finite amount of mass that must be added to the piston to hold it in equilibrium... -
Chestermiller replied to the thread Is this the correct general solution of the given PDE?.If your solution satisfies the differential equation, then it must be correct. (assuming y is the only other independent variable... -
Chestermiller replied to the thread Chemistry Understanding Reaction Quotient and Molarity.Here is an example. If you initially have 1 mole of H2 and 1 mole of I2, and you let the reaction to to equilibrium, forming x moles... -
Chestermiller replied to the thread Pressure difference between two points in a tapered pipe.Are you saying that there is no effect of the fluid velocities at the two points? -
