GIVEN:
L = 3.0 cm = 0.03 m
r = 0.3 mm = 0.0003 m
(delta) y = 1.0 m
1 pint = 500 cm^3 [approx.] given
a) Find the rate of flow, F = ?
b) How long will it taken to inject 1 point of blood,
t = ?
a & b) I know we need to find the pressure or speed.
F = (P at) (A) = (P at ) (pie) r^2
F = (1.01E5 Pa)(0.3 m)^2 (?)
? = I'm thinking to include 0.03 m and just put
(0.3 m)(0.03 m)
(delta) p = (density, roy) g (delta) h
I'm pretty sure we should use density of the blood
P1 - P2 = 8 (pie) n (multiply) vL/A
I'm trying every equation and can't see to get the right answer. But I know we need to have either speed or pressure to find the other and then we can be able to find time. I really need help on this one problem, thank you very much for any help
I'm wondering if I use this equation
v = (square root) (2gh) and then find the pressure and time
