![]() LT 1 On solving we get, Dimensional formula for ML1T1ML1T1 and it is equivalent to Kg m -1 s -1 The Viscosity of Water in SI Units The coefficient of viscosity of water can be determined by using Poiseuille’s law. The Poiseuille Equation in Viscosity of Liquids Poiseuille studied the flow of liquids through capillaries and deried an expression for the co-efficient. ![]() Plug your measurements into the equation to calculate the viscosity of the liquid. Since, the formula for coefficient of viscosity is given by, F. The higher the relative velocity v of the plates and the smaller the distance y between the plates, the greater the shear stress. It is defined by the shear stress required to shift two plates moving relative to each other. (ii) Internal tangential force which try to retard the relative motion between the layers is called viscous force.į = ± η A \(\frac\)įeel the extremely difficult topics too quite easy by accessing the concerned formulas from and clear your doubts. Calculate viscosity of liquid from the data you have collected: Viscosity (2 x (ball density liquid density) x g x a2) ÷ (9 x v), where g acceleration due to gravity 9.8 m/s2, a radius of ball bearing, and v velocity of ball bearing through liquid. Dynamic Viscosity Formula for the fluid will define its internal resistance to flow due to some shearing force. Viscosity describes the internal resistance to flow of a fluid (internal friction). ![]() (i) The property of the liquid by virtue of which it opposes the relative motion between its adjacent layers is known as viscosity. THE Einstein equation E E0(1 + 2.5 V) relating the viscosity E of a suspension of solid spheres and E0 the viscosity of the dispersion medium, V being the.
