Fluid friction formula
WebWhether a flow is laminar or turbulent depends of the relative importance of fluid friction (viscosity) and flow inertia. The ratio of inertial to viscous forces is the Reynolds number. Given the characteristic velocity scale, U, and length scale, L, for a system, the Reynolds number is Re = UL/ν, where ν is the kinematic viscosity of the fluid. WebFeb 9, 2024 · Question 2. Coefficient of sliding friction on a body is 0.5 and the normal force applied is 200 N. Find the force due to sliding friction. Solution: N = 200 N. μ = 0.5. F= μ × N. F = 0.5 × 200 N = 100 N. So, sliding friction applied on body is 100N. Question 3. What does sliding friction depend on? Answer:
