A constant-thickness film of viscous liquid flows in laminar motion down a plate inclined at angle 0, as in Fig. P4.36. The velocity profile is u =Cy(2h-y) v=w=0 Find the constant C in terms of the specific weight and viscosity and the angle 0. Find the volume flux Q per unit width in terms of these parameters.
Answered: Viscous liquid, at volume flow rate Q.… | bartleby
Viscous liquid, at volume flow rate Q, is pumped through the central opening into the narrow gap between the parallel disks shown. The flow rate is low, so the flow is laminar, and the pressure gradient due to convective acceleration in the gap is negligible compared with the gradient caused by viscous forces (this is termed creeping flow).

A colorless, viscous liquid, has a molar mass of 90. g/mol. Elemental analysis shows that this compound is 40.0 % carbon, 6.71% hydrogen, and the rest is oxygen. Determine the molecular formula of the compound in C-H-O order. For example, the formula C2H6O would be entered as C2H6O or C2H6O1

2- A test projectile is fired horizontally into a viscous liquid with a velocity 100 m/s. The retarding force is proportional to the square of the velocity, so that the acceleration becomes a =-0.8v². Derive expressions for the distance D traveled in the liquid and the corresponding time t required to reduce the velocity to 50 m/s.

A belt moves upward at velocity V, dragging a film of viscous liquid of thickness h as shown in the figure. Gravity is aligned with negative y direction. Near the belt, the fluid moves upward due to no-slip.

A viscous liquid (u = 0.012 lb-s/ft², p 1.79 slugs/ft³) flows through the annular space between two horizontal, fixed, concentric cylinders. If the radius of the inner cylinder is 7.5 in. and the radius of the outer cylinder is 8.5 in., what is the pressure drop along the axis of the annulus per foot when the volume flowrate is 0.14 ft³/s ...

A viscous liquid is sheared between two parallel disks of radius R, one of which rotates while the other is fixed. The velocity field is purely tangential, and the velocity varies linearly with z from V θ = 0 at z = 0 (the fixed disk) to the velocity of the rotating disk at its surface (z = h). Derive an expression for the velocity field ...

A constant-thickness film of viscous liquid (SG = 0.8, μ = 0.5 Pa-s) flows down an inclined plate an angle of 10° as shown in the figure The velocity profile is given by the equation, u(y) = Cy(2h - y). If the value of h is 5 cm, what is the value of the maximum velocity in m/s? NOTE: The pressure does not vary along the flow direction.
