Coeff of viscosity of water

WebSutherland's formula can be used to derive the dynamic viscosity of an ideal gas as a function of the temperature. The dynamic viscosity equals the product of the sum of Sutherland's constant and the reference temperature divided by the sum of Sutherland's constant and the temperature, the reference viscosity and the ratio to the 3/2 power of ... In fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. It is used in the drag equation in which a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag. The drag coefficient is always associated with a particula…
