Feel dumb now, I was up awake for an extremely long stretch of time and read the equation wrong... in my mind somehow the variable subscripts were flipped. I am not confused after a good night's rest :D

I'm trying to model a Transfer function for the response of the deviation in temperature of water coming out of the concentric tube heat exchanger in response to an input velocity of water function. THE PROBLEM I start the derivation with a couple equations in Seborg's Process Dynamics...

Homework Statement Calculate the uncertainty product ΔrΔp for the 1s electron of a hydrogen-like atom with atomic number Z. (Hint: Use <p> = 0 by symmetry and deduce <p^2> from the average kinetic energy) Homework Equations All I have is the wavefunction. For a 1s, it takes the form...

A couple questions: is mass quantized? Energy is quantized, and momentum has eigenvalues for its operator so I took that to mean that momentum is also quantized. If those two are true (might not be! I'm new to this :-p), following E^2 = (pc)^2 + (mc^2)^2 Would that not mean that mass is...

Thank you!

So let me if I understand you correctly, The reaction isn't occurring while the gas is diffusing, thus Ra isn't included in the differential equation. However it is introduced when we consider our boundery condition? Something along the lines of: -D(dCa/dr) = kCa at r=R2 Is that...

Homework Statement Not looking for solutions, just confused with the problem set up. Need help with the boundary conditions. Here it is: A porous ceramic sphere of radius R1 is kept saturated with a pure component liquid A. The vapor pressure of A is 50 torr. This sphere is surrounded by a...

I'm going to change my assumption for velocity in the x-direction. The fluid would be coming from both the top and bottom of the pipe and meet in the middle, where vx=0. Obviously this means there's a change in the x-direction with the x-component of the velocity. so now vx is a function of x...

Homework Statement Steady, laminar flow of an incompressible Newtonian fluid with constant physical properties. The area of interest in the problem is in the entrance region between two wise, horizontal parallel plates separated by distance 2B. z is in the direction of flow and x is the...
