Poiseuille's Equation for Blood Flow

Go Blood Flow = ((Final Pressure of System-Initial Pressure of Blood)*pi*(Radius of Artery^4)/(8*Length of the Capillary Tube*Density))

Pulse Wave Velocity using Moens-Korteweg equation

Go Pulse Wave Velocity = sqrt((Elastic (tangent) Modulus at Blood Pressure P*Thickness of Artery)/(2*Blood Density*Radius of Artery))

Pressure Drop using Hagen-Poiseuille equation

Go Difference in Pressure = (8*Viscosity of Blood*Length of the Capillary Tube*Blood Flow)/(pi*(Radius of Artery^4))

Elastic (Tangent) Modulus using Hughes equation

Go Elastic (tangent) Modulus at Blood Pressure P = Elastic Modulus at Zero Blood Pressure*exp(Material Coefficient of Artery*Blood Pressure)

Frank Bramwell-Hill equation for Pulse Wave Velocity

Go Pulse Wave Velocity = sqrt((Volume*Difference in Pressure)/(Blood Density*Change in Volume))

Mean Velocity of Blood

Go Mean Velocity of Blood = (Viscosity of Blood*Reynolds Number)/(Blood Density*Diameter of Artery)

Reynolds Number of Blood in Vessel

Go Reynolds Number = (Blood Density*Mean Velocity of Blood*Diameter of Artery)/Viscosity of Blood

Viscosity of Blood

Go Viscosity of Blood = (Blood Density*Diameter of Artery*Mean Velocity of Blood)/Reynolds Number

Pulsatility Index

Go Pulsatility Index = (Peak Systolic Velocity-Minimum Diastolic Velocity)/Average Velocity in terms of Cardiac Cycle

Mean Arterial Pressure

Go Mean Arterial Pressure = Diastolic Blood Pressure+((1/3)*(Systolic Blood Pressure-Diastolic Blood Pressure))

Pulse Pressure

Go Pulse Pressure = 3*(Mean Arterial Pressure-Diastolic Blood Pressure)
