1. For flow at very low speeds and with large viscosity (the so-called creeping flows) such as occur in lubrication, it is possible to delete the inertia terms, Dv/Dt, from the Navier- Stokes equation. For flows at high velocity and small viscosity, it is not proper to delete the viscous term μ∇2v. Explain this.
2. Using the Navier-Stokes equations and the continuity equation, obtain an expression for the velocity profile between two flat, parallel plates.
