(a) For laminar draining of a wide thin sheet of water on pavement sloped at angle θ, as in Fig. P4.36, show that the flow rate is given by where b is the sheet width and h its depth
(b) By (somewhat laborious) comparison with Eq. (10.13), show that this expression is compatible with a friction factor f = 24/Re, where Re = Vavh/ν.
