Question

2.59 As shown, glycerin at 20°C is flowing in a channel, and the pressure gradient dp/dx is -1.2 kPa/m. What are the velocity and shear stress at a distance of 11 mm from the wall if the space B between the walls is 5.0 cm? What are the shear stress and velocity at the wall? The velocity distribution for viscous flow in a channel is u = -1/(2?) * dp/dx * (By - y^2)

Step 1

Given: Pressure gradient (dp/dx) = 1.2 kPa/m Distance from the wall (y) = 1 mm = 0.001 m Channel width (B) = 5.0 cm = 0.05 m Using the velocity distribution equation for viscous flow in a channel: v = (1/2) * dp * (B - y^2) / dx Substituting the given values: v Show more…
