Darcy's law is valid for only
Web4.1.What are the assumptions for Darcy’s law to be valid? Discuss each of them. Solution 4.1 The key assumptions are 1. Steady flow. The flow is constant over time. 2. Laminar. Only applied to non-turbulent flow with Reynolds number less than about 1. 3. Inviscid. The viscosity remains constant so temperature and pressure are constant. 4. WebBy calculating all types of soil, Darcy’s law is valid only for clay, silt and sand and not for gravels, cobbles etc. This is because the flow is always turbulant. Under what conditions …
