Poiseuille's Equation Flashcards
1
Q
defines relationship between
A
pressure, volume flow, resistance
2
Q
helps define how much
A
fluid volume moves through vessel
3
Q
Q = P/R
A
1: volume flow
p: pressure
r: resistance
4
Q
Q = (P1-P1) pie r ^ 4
________________
8 n L
A
Q= volume flow P= pressure at prox/ dist ends R= radius L=length n=viscosity
5
Q
has most dramatic effect on resistance
A
diameter change
6
Q
radius is ______ proportional to volume flow
A
directly
7
Q
small changes in radius may result in
A
large changes in volume flow
8
Q
the law of conservation of mass explains the relationship between
A
velocity and area
9
Q
lat of conservation
A
q = a x v
10
Q
A =
A
decreased velocity
11
Q
B =
A
increased velocity
