Question: How do I get a transfer function into a standard form?

Hi I have a transfer function first or second order and I want to get it into standard form

Which the transfer function is

of H(s)/(W__I(s) so how height of a tank (H) is affected by incoming flow rate (W__i(s)) but I need to get this transfer function into standard 1st order form

Where I need to find what K and tau are to get it in to this form and tau is always in the units of time. How can I do this in maple? It's pretty impossible by hand I find. I've attached my workbook for it.
