State newton's law of viscosity?
viscosity is the quantity that describes a fluid's resistance to flow. Fluids resist the relative motion of immersed objects through them as well as to the motion of layers with differing velocities within them. Formally, viscosity (represented by the symbol η "eta") is the ratio of the shearing stress (F/A) to the velocity gradient (Δvx/Δz or dvx/dz) in a fluid. η = ⎛⎜⎝ F ⎞⎟⎠ ÷ ⎛⎜⎝ Δvx ⎞⎟⎠ or η = ⎛⎜⎝ F ⎞⎟⎠ ÷ ⎛⎜⎝ dvx ⎞⎟⎠ A Δz A dz The more usual form of this relationship, called Newton's equation, states that the resulting shear of a fluid is directly proportional to the force applied and inversely proportional to its viscosity. The similarity to Newton's second law of motion (F = ma) should be apparent. F = η Δvx or F = η dvxA Δz A dz ⇕ ⇕ F = mΔv or F = m dv Δt dt The SI unit of viscosity is the pascal second [Pa·s], which has no special name. Despite its self-proclaimed title as an international system, the International System of Units has had very little international impact on viscosity. The pascal second is rarely used in scientific and technical publications today. The most common unit of viscosity is the dyne second per square centimeter [dyne·s/cm2], which is given the name poise [P] after the French physiologist Jean Louis Poiseuille (1799-1869). Ten poise equal one pascal second [Pa·s] making the centipoise [cP] and millipascal second [mPa·s] identical. 1 pascal second = 10 poise = 1,000 millipascal second1 centipoise = 1 millipascal second
How do you convert from pascal seconds to centistokes for viscosity?
Centipoise divided by specific gravity is equal to centistokes. Centipoise divided by specific gravity is equal to centistokes. Centipoise divided by specific gravity is equal to centistokes. Centipoise divided by specific gravity is equal to centistokes.
Where does the viscosity of magma depends?
1. Chemical Composition of the magma. 2. Concentration of the melt. 3. Presence of Volatiles. 4. Amount of Water present in the magma.
What is the viscosity of saltwater?
At 30 degrees Fahrenheit, the viscosity of sea water is typically around 1.880 centipoise. (1 centipoise = 0.001 Pa·s = 1 mPa·s) --------------------------- Viscosity is 1.88? is there any reference please?
What is the viscosity of a dilute dispersion of silica particles in water?
Dilute? Less than .1% I would guess viscosity of Water
What is the SI unit of kinematic viscosity?
Kinematic viscosity is the ratio of dynamic viscosity to density of the fluid. The SI unit of the quantity is square meter per second (symbol m²/s). The most frequent used unit of kinematic viscosity is Centistokes (cSt). 1 Centistokes (cSt) is the kinematic viscosity of a fluid with dynamic viscosity of 1 cP and volumic mass 1 g/cm³.
Si unit of coefficient of viscosity?
The Si unit for viscosity is Pa·s = kg/(s·m).
What is the Viscosity of Cerebrospinal Fluid?
0.7-1 mPa*s (or cP).
What is the viscosity of asphalt?
Viscosity - The ratio between the applied shear stress and the rate of shear is called the coefficient of viscosity.This coefficient is a measure of the resistance to flow of the liquid. It is commonly called the viscosity.The SI unit of viscosity is the Pascal second (Pa•s). Another common unit of viscosity is the centipoise (cP) where 100 cP is equal to 1 Poise (P), and 10 P = 1 Pa•s.
What is the measure of resistance to the flow of fluid?
When fluids-- liquids or gases-- move through pipes or ducts, they meet resistance. Resistance occurs because outer layers of the fluid are "held back" by a friction-like force as the layers slide by the walls of the pipe or duct. Resistance occurs also between fluid layers within the fluid as they slide past one another. Whatever the cause, fluid resistance in a pipe or duct affects both (1) flow rate and (2) pressure drop along the pipe.

What is the difference between fluid viscosity?
Some fluids are more denser than other fluids. For example, shampoo is more denser than Ketchup or oil or water. Therefore, it has a higher viscosity! The thick/denser/sticker a fluid is the higher the concentrtation of viscosity. Here is a range of some fluids put from high viscosity to low concentration of viscosity: 1: Shampoo 2: Ketchup 3: Corn oil 4: Water Water has a really low concentration of viscosity.

Various drilling mud have the same apparent viscosity at 1022sec-1 but the effective viscosity at other shear rates may vary widely Explain?
Drilling mud is a nonnewtonian fluid. It's a thixotropic fluid and it's apparent viscosity is a function of shear rate and time so at various shear rate and times you will have various viscosities. The molecular structure of these fluids breaks during tention.For further informations you can refer to rheology or fluid mechanics books.

What is the viscosity of chocolate milk?
at pasteurization temperature the best estimate was 0.7. With Xanthan Gum the estimate was 0.5. However, there are variations, the fat content can can affect viscosity for example What unit of measurement is the above estimate of 0.7 to 0.5?
