All the geotech programs I applied for are civil engineering programs, just with a concentration in geotechnical applications.

I have a bachelors in geophysics and am currently deciding between attending a school for a masters in geoscience/geophysics and attending a school for a masters in geotechnical engineering. They are both funded to a degree, with the geoscience masters being extremely well funded versus the...

Ah sorry, those values refer to a coarse aggregate not conrete. The aggregate has a density of 167 and a unit weight of 103 with the same exact units. I guess the question is the same though, in my notes, the lectures, and my laboratory hands outs the density and unit weights are always...

In my lectures and notes my professor keeps writing out density as lbs/ft3 and unit weight as lbs/ft3. For a material such as concrete it could have a density of 167 lbs/ft3 but a unit weight of 103 lbs/ft3. I am confused as to how these two values are different even though they have the exact...

I've come across two different approaches to quantifying what l is in the equation for hydraulic gradient Δh/L. In this first picture L is the parallel distance along the datum across the reference plane But in this second picture L is the length along the pipe Why are the two L's...

Just so I am understanding this, by changing the radius of the sphere I am essentially changing the Reynolds number and thus the associated drag force? Are same shaped objects scale-able in terms of their drag force and drag coefficient or would I have to do separate experiments for both?

If velocity, density, and viscosity are kept constant, would Reynolds number change? It shouldn't as long as the diameters of the testing pipe stay the same right?

I've read that drag coefficient depends on the shape of the object but I am confused as to what shape means. Does it mean geometric shape or is area included in that? Say I have one sphere of radius r and keep fluid velocity, density, and viscosity constant and find its drag coefficient. Would...

Hmm, I just checked the given values of the mass of a proton and electron from the book I have (where the question is from) and I notice that the given mass of the 1 H and what can be added from the following data does not add up. proton: 1.007276 u electron: 0.00054858 u p+e=1.00782 which...

Ooh I see. The lack of neutron means I can neglect binding energies. That makes much more sense thank you.

A hydrogen atom is one proton and one electron if I remember correctly. Am I supposed to derive the mass of p and e from this?

Homework Statement Given that the mass of 1 H is 1.00794 amu, the mass of a neutron is 1.00865 amu and that the energy equivalent of 1 atomic mass unit (AMU) is 931.5 MeV, what is the binding energy of 12C (atomic mass = 12.00000 amu)?Homework Equations (σ) mass decrement=(W) mass of...

Thanks for the insight. This is turning out to be a very informative thread. There is one issue I should probably raise up though that I should have in the beginning: I am not a physics major. I am an Earth and planetary science major that simply has to take physics (my last pure physics class I...

People list the number of classes they took on job applications? :O I was under the impression that asking for a transcript wasn't a very common thing in industry but I guess it depends on where and what...

This is quite interesting. Would you care to elaborate on some of these points? For number 1, how exactly can taking less units backfire on me? Perhaps lazyness or apathy might set in but I don't plan to "take it easy" by taking less units, I'm simply freeing up my schedule in a manner I think...
