• Flux = D x [(C outside - C inside)]/d

• F = V/t

• Flow = cross sectional area x mean velocity

• Pressure = Force/Area

• Pressure = density x g x height

• P = P in - P out 

• Flow = Perfusion Pressure/ Resistance 

• R = 8vL/pi(r)^4

• R=R1+R2...

• R= 1/R1+1/R2 ...

• SV = EDV - ESV 

• EF (%) = SV/EDV

• CO = SV x HR

• Pulse Pressure = Systolic - Diastolic

• MAP = Diastolic + 1/3 pulse pressure

• Flow = MAP/R

• TPR = MAP x CO

• MAP = CO x TPR

• MAP = HR x CO x TPR

• V=I x R
