Using dimensional analysis, express the characteristic length, velocity and time scales for near-wall flow in terms of the density, viscosity and wall shear-stress. Show that the length scale can also be expressed as where v is the kinematic ur viscosity and u, is the friction velocity.

Consider a two-dimensional, fully-developed, steady viscous flow of water through a duct of constant one-centimeter width in the y-direction. There is no pressure variation through the flow but the water flows in the positive x-direction, which is the direction of the gravity force. $y = 0 and gx = g. (a) Using the continuity and momentum equations, determine the magnitude of the v component of velocity and develop the ordinary differential equation that governs the u component of velocity. (b)...

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...
