"WebThe loss of head per unit distance of flow (or along the length of flow) is called hydraulic gradient. It is denoted by ‘I’ I = h/L ADVERTISEMENTS: Where h = head loss L = length along the flow path over which head loss is h. Darcy’s Law: In the mid-eighteenth century H. Darcy working in Paris studied experimentally the flow of water through soil. " - Falling head permeability test graph
