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.
-
Chestermiller replied to the thread A Condensate rate of water for an air conditioning cooling coil.You need to be able to calculate the outlet temperature of the condenser. For this, you need to know the heat transfer coefficient...

In that scenario, the component of velocity in the y direction remains constant. It would not reduce to zero.

Chestermiller replied to the thread I I need to simulate clothing meshes for hanging garments.Can the fibers slide at the crossovers or are they locked?

Chestermiller reacted to BvU's post in the thread A Should the boundary condition have to satisfy dimensional consistency? with Like.
Yes

Chestermiller replied to the thread Reconcile poundforce w/slug and lbmass.No. The 32.2 is fixed. And the measured force at the equator would be < 1 lb.

Chestermiller replied to the thread Solubility of MgSO47H2O in water.Maybe they counted the water of hydration as part of the total water.
