Chestermiller's latest activity
-
Chestermiller replied to the thread I What thermal cycle would describe the action of a candle carousel?.There is no cycle involved. You simply heat the air and gases to cause them to expand and make the propeller above to rotate. -
Chestermiller replied to the thread B Basic thermal energy transfer physics: Insulation value in open airways vs sealed airways.I assume that the heat flow is in the vertical direction and the bottom is hotter than the top, so we do not need to include natural... -
Chestermiller replied to the thread Correct statement about siphon used to empty water tank.At the maximum hight of the siphon, when cavitation occurs, the absolute pressure is not zero, It is equal to the vapor pressure of the... -
Chestermiller replied to the thread I Non-orthogonal bases.In analyzing the mechanics of deformable membranes (such as, for example, the deformations and stresses within an automobile tire... -
Chestermiller reacted to Borek's post in the thread Humidity of a saturated NaCl solution with anticaking additive with
Like.
Unless my English fails me big there is no such thing as "humidity of a solution", I suppose you mean "humidity of the air saturated... -
Chestermiller replied to the thread Physics of Stretch: What pressure does a band apply on a cylinder?.In scenario 2, the radius of the cylinder is found by ##2\pi R=1.2##or $$R=\frac{1.2}{2\pi}=\frac{0.6}{\pi}$$The pressure is given by... -
Chestermiller replied to the thread Physics of Stretch: What pressure does a band apply on a cylinder?.In the first scenario, there is definitely going to be significant widthwise contraction (and this would reduce the required tensile... -
Chestermiller replied to the thread I Entropy and configurations of microstates.In statistical thermodynamics, the following approximation is frequently used: $$\ln{(n!)}=\ln(1)+\ln(2)...\ln(n-1)+\ln(n)\approx... -
Chestermiller replied to the thread Physics of Stretch: What pressure does a band apply on a cylinder?.Is the allowed to contract in width when scenario 1 is applied? Is it allowed to contract in with what scenario 2 is applied? -
Chestermiller replied to the thread Enthalpy - published values.This is not a correct interpretation. The difference between H2O l enthalpy and H20 g enthalpy is primarily the result of the... -
Chestermiller replied to the thread Enthalpy - published values.I totally oppose introducing this description in an attempt to assign a physical interpretation to enthalpy. I have seen it accomplish... -
Chestermiller reacted to boneh3ad's post in the thread Query on Isentropic relationships (such as PV^gamma = constant) with
Like.
You are correct, it does not apply to adiabatic, irreversible processes. But that's kind built right into the word itself: isentropic... -
Chestermiller replied to the thread Cantilever help.Let's see you analysis so far, starting with your schematic of the system.
