    I really need some advice

    I loved it when I was in Alaska, so Alberta would work for me. But for her it might be way too cold.

    I really need some advice

    She has a BS in chemistry, not engineering. Everybody make that mistake. It's tough to find a good chemistry job around here... or anywhere.

    I really need some advice

    I don't believe I can leave New England. What will happen if I have to sit in a job that does no engineering while looking for a job that does? I could be here for years waiting and looking.

    I really need some advice

    I have a BS in Electrical Engineering from Northeastern University. When I graduated in 2006, I left the school with $80k in loans. I took a job with the Naval Undersea Warfare Center (NUWC) in RI, and have been working there for the past 5+ years. The reason I took the job was because of loans...

    "NON"-Constant surface heat flux in Internal Forced Convection in Pipe

    I've made some progress with this problem. I've developed two solutions: one is an algebraic extension of constant heat flux, and the other is an FDM solver for the governing PDE. Question: Assuming laminar flow, incompressible fluid, the PDE is v0*cp*rho*(1 - r^2/R^2)dT/dx = k*Laplacian(T)...

    "NON"-Constant surface heat flux in Internal Forced Convection in Pipe

    IRstuff, On the contrary, I am designing a microfluidic temperature/flow sensor... it acts kind of like a solid-state hot wire anemometer. Imagine fluid flowing through a channel cut into a material with a high positive-temperature-coefficient. On each side of the channel are two pairs of...

    "NON"-Constant surface heat flux in Internal Forced Convection in Pipe

    Ugh. It bothers me that there is no analytical solution.

    "NON"-Constant surface heat flux in Internal Forced Convection in Pipe

    prex, Making the assumption of radial temperature is acceptable. I'll re-work my posted diagram to make sure I understand your advice. Thanks. Once I get this part down I'll try to use FDM to move forward.

    "NON"-Constant surface heat flux in Internal Forced Convection in Pipe

    I've posted a diagram of my problem. http://files.engineering.com/getfile.aspx?folder=deac7719-0943-48b6-a6fc-4a02c19207b4&file=pipe_heattransfer.pdf See attachment...http://files.engineering.com/getfile.aspx?folder=deac7719-0943-48b6-a6fc-4a02c19207b4&file=pipe_heattransfer.pdf

    "NON"-Constant surface heat flux in Internal Forced Convection in Pipe

    Chapter 9 is Natural Convection. I did not read this chapter yet. I will, and then I'll post an illustration of my problem on Monday (tomorrow).

    "NON"-Constant surface heat flux in Internal Forced Convection in Pipe

    I am an electrical engineer and I just finished reading "Introduction to Heat Transfer" by Incropera and DeWitt. I am new to heat transfer. I want to find what the internal surface temperature of a pipe is as a function of axial distance from the inlet (assuming incompressible fluid with...
