    Need some helps for a Heat Exchanger Optimization project

    6) Some equations we have considered to use: ##q = C_h (T_{h,o} - T_{h,i}) = C_c (T_{c,i} - T_{c,o})## ##C_h = \dot m_{water} c_{ph}## , ##C_c = \dot m_{air} c_{pc}##, ##c_{ph}## and ##c_{pc}## are specific heat capacity of water and air respectively ##NTU = \frac{UA}{C_{min}}## NTU is...

    Need some helps for a Heat Exchanger Optimization project

    Hello fellow PF members, My teammates and I are working on a project in our Heat Transfer class. It is extremely broad (open ended) and we are not very sure how we should get this project up and going. 1) Project description: We are given an Air Cooled Rankine Cycle. Cooling water, at 70 °C...

    M.S. Mechanical Engineering in Mechanics vs Robotics/Controls

    Hello fellow PF members, I'm currently in my senior year in Mechanical Engineering at Oregon State University. I'm considering going on to get my Master's Degree to gain more knowledge (since I'm fascinating by them). I really like Math and have a Math Minor already. I am looking to go into a...

    B.S. in Mechanical Engineering, where should I go from here?

    I guess my previous post was long and rather vague. My problem is that I like everything that I have learned up to this point in Mechanical Engineering (except for Design and Materials Science). After thinking for a few days, I have narrowed down to just Mathematical modeling/simulation and...

    B.S. in Mechanical Engineering, where should I go from here?

    Hello fellow PF members, Some background about me: I am currently a senior (actually is my 6th year in college) in Mechanical Engineering at Oregon State University. I am on track and will be graduating next summer. Given how long I have been in college, I would want to go straight to work...

    Integrating factor for a 2nd order homogeneous linear ODE

    Thank you so much, BruceW! :) So I went back to this step: Py'' + Qy' + Ry = μPy'' + (μP' + μ'P)y' + μRy, and then grouping like terms of y'', y', and y. And then I use the relationship from Eq. (1) then I'm left with just y'. So, yes, I got the answer as the book stated. Thanks so much for...

    Integrating factor for a 2nd order homogeneous linear ODE

    Homework Statement Consider the general linear homogeneous second order equation: P(x)y'' + Q(x)y' + R(x)y = 0 (1) We seek an integrating factor μ(x) such that, upon multiplying Eq. (1) by μ(x), we can write the resulting equation in the form [μ(x)P(x)y']' + μ(x)R(x)y = 0...

    A question on linear algebra text

    Alright, so far I think I have the following choices: _ Linear Algebra and Its Applications by David C Lay _ Linear Algebra Done Right by Axler _ Either Introduction to Linear Algebra or Linear Algebra and Its Applications by Gilbert Strang _ Matrix Analysis and Applied Linear Algebra by...

    A question on linear algebra text

    Thanks for your replies! I actually looked in the forum, and there are bunches of different opinions on each book. Most recommended was the book by Axler, but I don't know if that is too advanced for me right now. Others suggest a book by Huffman and Kuzne, a book from quite a long time ago...

    A question on linear algebra text

    A question on linear algebra text! Hello everybody! I'm new to this forum. Actually, this is my first post in here. I'm currently a sophomore student in college. My major is in mechanical engineering. Right now, I'm taking the course introductory linear algebra, which is the first course in...
