    Comparing GRE and Physics GRE: Tips and Book Recommendations

    I thought that the actual GRE was easier than the pGRE test I took. I was scoring in the mid 600's on the Q and in the 300's in the V on the practice tests and ended up scoring 740 Q and 490 V on the real thing. I also used the Manhattan GRE which I found to be more challenging that any other...

    PV diagrams for heat engines are legitimate ?

    Actually the speed of the engine doesn't effect thermodynamic equilibrium unless the pistons are moving faster than the speed of sound. If they are moving faster than the speed of sound then yes your correct equilibrium will not be met becuase the air molecules ,so to speak, don't "see" the...

    How exactly does a gas turbine engine produce thrust?

    ...So the question is, what exactly is the nozzle doing? the nozzle increases velocity which increases thrust. thrust is defined as mdot x V so increasing v increases the thrust.

    Calculating Maximum Cycle Temperature in Carnot Cycle | Homework Solution

    Carnot Efficiency is n=1-(Qc/Qh), Qc is heat rejected, Qh is heat supplied also Carnot efficiency is n=1-(Tc/Th) Drawing a control volume around the device, (20 KW + 12 leaving) means 32 input or Qh=32, thus you have an efficiency, and then you can use this efficiency to solve for Th So...

    What are the Appropriate Orifice Sizes for Uniform Exit Temperatures?

    Am I correct in saying that the air is heated inside the compartment? I will assume that I am. for started let's make a control volume. Say we make a control volume around one compartment. We know by conservation of mass that mdotin=mdotout, and that Q=mdot*cp*dt, where dt=To-Ti. So if we say...

    What are the Appropriate Orifice Sizes for Uniform Exit Temperatures?

    you are going to have to be a little more specific here. Internal flow, external flow, modes of heat transfer? you clearly must be confused, you need to learn how to ask the right questions

    How difficult is Aerospace Engineering

    I am considering going to graduate school for either ME or AERO. I know that I could handle ME considering it is what I got my degree in. I know that ME and AERO are similar but how competitive is AERO and how difficult is the course work? I am a good student. 3.11 from a tough school...

    Admissions Can I get into U of Minnesota's ME grad program with my credentials?

    MS Engineering. Odds? I am currently in the process of applying for the U of Mn ME grad program. I am wondering if anyone has experience applying to this school or a similar school and what there experience was. I have looked online at there requirements and meet them all but I know that this...
