1. An oil has a kinematic viscosity of 2 x 10^-4 m^2/s and a density of 0.8 x 10^3 kg/m3. If we want to have a falling film of thickness of 3 mm on a vertical wall, what should the mass rate of flow of the liquid be? Show all your steps for calculation along with how you arrive at equation for calculating the flow rate of mass. (Hint: In class, we derived the average velocity for a falling film on inclined plane. This problem is based on similar derivation).

Step 1
We are given: - Kinematic viscosity (\( \nu \)) = \( 2 \times 10^{-4} \, \text{m}^2/\text{s} \) - Density (\( \rho \)) = \( 0.8 \times 10^3 \, \text{kg/m}^3 \) - Film thickness (\( \delta \)) = 3 mm = 0.003 m Show more…

Consider steady, incompressible, parallel, laminar flow of a film of oil falling slowly down an infinite vertical wall inclined at an angle α as shown in the figure. The oil film thickness is h, and gravity acts in the negative z-direction. There is no applied (forced) pressure driving the flow — the oil falls by gravity alone. Calculate the volume flow rate per unit width (V/L) for an oil film of thickness 11 mm with ρ = 888 kg/m³ and μ = 0.80 kg/m·s. Take angle α as 60°.

a) Find the kinematic viscosity of oil having a density of 981 kg/m³. The shear stress at a point in oil is 0.2452 N/m² and the velocity gradient at that point is 0.2 per second. b) Define surface tension and bulk modulus.
