    a) in the case for which Tw=68.4 C = constant
    b) in the case for which qw=378 w/m^2 = constant
    Indicate x(et) on your graphs.

    Welcome to the forum.

    Here is how it works:

    1. Use the homework template, as you have to ask for help with homework questions.
    2. Show your attempt to solve the problem, which you have not done.

    Show your work and then someone here will help you. Don't just post questions and expect them to be answered for you.

    Thanks
    Matt
