Chestermiller replied to the thread Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property?.Here's a focus problem: I have a spherical shell of low density polyethylene of inner radius 10 cm and outer radius 10.1 cm. The shell... -
Chestermiller replied to the thread Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property?.Yes. Check out the phase diagram for water Phase Diagram of Water Also, the water experiences an increase in volume in the deformed... -
Chestermiller replied to the thread Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property?.The container could impose compressive stress on the ice which alters the thermodynamic relationship between ice and water, and can... -
Chestermiller replied to the thread Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property?.The volume expansion from water to ice is an intrinsic property of water specifically under the constraint of negligible confining... -
Chestermiller replied to the thread Graduate Need help with Henry's Law.Henry's Law tells us that the concentration of oxygen in the rubber at its outer surface is equal to the partial pressure of oxygen in... -
Chestermiller replied to the thread Engineering Engineering Timber Beam Stress Calculation Help.What are the parameters in your equations, and what criterion are you using for failure? -
Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.Counter current heat exchangers, flash vaporizers, cooling towers, heat pumps, refrigeration units, mixing with ice, ''' -
Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.Have you considered all possible scenarios. I think you should read up on the concept of exergy. -
Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.What do you mean by the term "cooling can be generated," and are you saying that this broad statement has no constraints? For example... -
Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.If I understand you correctly, right for an adiabatic process. -
Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.Here's a big surprise: The surroundings doing adiabatic compression work on a gas causes its internal energy and temperature to... -
Chestermiller replied to the thread High School Uniform thermal expansion of metals.From a fundamental materials point of view, if the metal is isotropic and the sample in not constrained or loaded mechanically... -
Chestermiller reacted to Ibix's post in the thread Graduate How valid is the Block Universe theory? with
Like.
It's an interpretation, so not testable as far as we know. It's far and away the most popular interpretation, and fits well with the... -
Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.Cooling by expansion can be done with less energy consumption than by what? This seems to me to be basically just a standard reversible... -
Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.Here are my calculations for scenario 1. Given: Initial Temperature = ##T_i=300.2K## Initial Pressure = ##P_i=101325\ Pa## Number of...
