comment Is this how I find the rate of change of internal energy for filling a vessel?
@KyleKanos how would I use the T-ds equation to find an expression for $\frac{ds}{dt}$? I wanted to use $T\frac{ds}{dt}=\frac{du}{dt}+P\frac{dv}{dt}$ but T in the tank is changing with time. And it doesn't look like i could apply the product rule to that since it's already in the differential form

yes i have all the variables. I just wanted to know if that step was right. I was given the expression for the change in pressure, and i determined change in $v$ with the ideal gas law. and i found dhdt by the energy balance

comment Thermal resistance of thermal interface materials?
@ThePhoton It all makes sense now that I remember the coolant is being constantly replenished and I assume it's a constant temperature. Thanks guys

comment Thermal resistance of thermal interface materials?
Lets say the chip needs to operate at $T_H$ and it dissipates constant 2 W. If we have a low total resistance, then doesnt that make the coolant temperature very close to $T_H$? But you just said you want it as low as possible. This is why I am getting confused

comment RMS Free Path vs Mean Free Path
I have no idea what to even do with that honestly. I am not a molecular physics guy. I just need to find a formula for RMS free path and there is nothing on google.

comment Molecular mean free path probability
I'm not really sure what kind of variable the $\xi$ is. It is just the distance the molecule will travel without a collision. I'm guessing it's continuous since it can be 0.01 or 0.012 or 0.013. Are you essentially saying that I should take "at least" and "greater than" to be the same?
