Equation of work

What are the formulas for work and power? That equation is:Work = Force • Displacement • Cosine(theta)W = F • d • cos(theta)Power = Work / time.P = W / t.P = F • cos(theta) • (d/t)P = F • v • cos(theta)PEgrav = m•g•h.KE = 0.5 • m • v2 What is a unit […]

Darcy’s equation

How is Darcy’s Law calculated? The hydraulic head is measured by determination of the vertical position of the water table in a well relative to a reference surface. Darcy’s law says that the discharge rate q is proportional to the gradient in hydrauolic head and the hydraulic conductivity (q = Q/A = -K*dh/dl). WHAT IS […]
