    Good day. I was wondering if you could help me solve this first order linear partial differential equation:

    [∂δ]/[/∂t] = [ρg]/[/μ] δ^2 [∂δ]/[/∂z].

    The solution for this is:

    δ(z, t) = √[μ z]/[/ρg t].

    I don't really understand how the PDE became like this. If you could show the step-by-step solution, I would really, gladly appreciate it. Thank you :)

    Welcome to the PF.

    Is this for schoolwork?
