Viscosity of Blood Solution

Follow our step by step solution on how to calculate Viscosity of Blood?

FIRST Step Consider the formula

μ = \frac{ρ blood \cdot D artery \cdot v}{Re}

Next Step Substitute values of Variables

∴

μ = \frac{11.5kg/m³ \cdot 10.55m \cdot 15.65mL/s}{5000}

Next Step Convert Units

∴

μ = \frac{11.5kg/m³ \cdot 10.55m \cdot 1.6E-5m³/s}{5000}

Next Step Prepare to Evaluate

∴

μ = \frac{11.5 \cdot 10.55 \cdot 1.6E-5}{5000}

Next Step Evaluate

∴

μ = 3.7974725E-07Pa*s

Next Step Convert to Output's Unit

∴

μ = 0.00037974725cP

LAST Step Rounding Answer

∴

μ = 0.0004cP

Variables

Viscosity of Blood

Viscosity of Blood is a measure of the resistance of blood to flow. It can also be described as the thickness and stickiness of blood.

Symbol: μ

Measurement: Dynamic ViscosityUnit: cP

Note: Value should be greater than 0.

Formulas to find Viscosity of Blood

Blood Density

The Blood Density is the mass per unit volume of blood.

Symbol: ρ_blood

Measurement: DensityUnit: kg/m³

Note: Value should be greater than 0.

Formulas to find Blood Density

Diameter of Artery

Diameter of Artery is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.

Symbol: D_artery

Measurement: LengthUnit: m

Note: Value should be greater than 0.

Formulas to find Diameter of Artery

Mean Velocity of Blood

Mean Velocity of Blood is the mean rate of blood flow through a given vessel. Blood flow is the volume of blood flowing through a particular vessel in given interval of time.

Symbol: v

Measurement: Volumetric Flow RateUnit: mL/s

Note: Value should be greater than 0.

Formulas to find Mean Velocity of Blood

Reynolds Number

The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.

Symbol: Re

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.
