... 4) The drag force FD on a washer-shaped plate placed normal to a stream of fluid can be expressed as FD = f(d1, d2, V, μ, ρ) where d1 is the outer diameter, d2 the inner diameter, V the fluid velocity, μ the fluid viscosity, and ρ the fluid density. Some experiments are to be performed in a wind tun ...

... a reversible interchange with strain energy, p Θ = −( p / ρ )( D ρ / Dt ) , (ii) a dissipation by viscous forces, − ⎡⎣(λ + 2µ ) Θ 2 − 4µ Φ ⎤⎦ Since Θ 2 − 2Φ is always positive, this last term is always dissipative. If Stokes’ relation is used this term is ...
