Chestermiller replied to the thread Expansion or compression -- which is more energy efficient?.A pressure of 1 kg/cm^2 corresponds to ##0.98\times10^5\ Pa## pressure. From the ideal gas law, for 1 mole gas at 300 K, the ideal gas... -
Chestermiller reacted to haruspex's post in the thread If Heat Is Motion, Why Isn’t All Motion Heat? with
Like.
Is that the exact wording of the question? I ask because in scientific usage "heat" only refers to the transfer of energy between... -
Chestermiller replied to the thread Construction of a model of a hydraulic damper.Is this an existing physical piece of equipment that you can perform experiments on, or is it a schematic of a damping concept that you... -
Chestermiller replied to the thread Construction of a model of a hydraulic damper.Are you familiar with lubrication flow analysis? Do you know how to solve the problem of laminar flow between two infinite parallel plates? -
Chestermiller replied to the thread Construction of a model of a hydraulic damper.I would first derive and solve the equations for the fluid dynamics of the system. Do you know how to solve axial annular laminar flow... -
Chestermiller replied to the thread Construction of a model of a hydraulic damper.The viscous damper I described in post #2 does not require CFD analysis to quantify its behavior. It can solved analytically for the... -
Chestermiller replied to the thread Construction of a model of a hydraulic damper.I'm thinking of a cylinder with a piston in which the clearance between the piston and the cylinder wall is finite. The piston is long... -
Chestermiller replied to the thread Construction of a model of a hydraulic damper.Damping is often approximated using an ideal dashpot. Is that what you are searching for: an approximate equation for the dashpot... -
Chestermiller replied to the thread Need help with pressurized air.100% RH means that the partial pressure of the water in the tire is equal to the equilibrium vapor pressure of water at the air... -
Chestermiller replied to the thread Undergrad Difference calculating enthalpy change by using thermodynamic table A-17 vs. A-2 with integration.The table in the first method used integration with respect to temperature also. It would seem to be a matter of the difference in the... -
Chestermiller replied to the thread Spring aproximation.Yes, neglecting dissipation factors such as air drag.
