Explanation The definition of the coefficient of viscosity is η = F d / A v and this expression is rearranged for F = η A v / d . Given info : The viscosity of water is 1.79 × 10 − 3 N ⋅ s/m 2 , thickness of water is 0.10 mm , sides of the ice block is 1.20 m and 0.800 m , and the speed of the block is 0.50 m/s . The formula for the magnitude of the force needed to pull the block with a constant speed is, F = η A v d η is viscosity of water. A is area of the block. v is speed of the block. d is thickness of the block. Substitute 1.79 × 10 − 3 N ⋅ s/m 2 for η , 1.20 m × 0

Viscosity

The measure of the resistance of a fluid to flow is known as viscosity. Most fluids have some resistance to motion, the resistance provided by the fluid is called viscosity. This resistance is created by the force of attraction between the fluid molecule…
