Oh you're right, sorry. Yeah they are circular pipes but I just wrote down the area incorrectly. I wrote down the pipes' radii for their area when I shouldn't wrote their radii^2*pi. Thanks for the help!
Hi,
I am working on this water pressure problem,
given:
v_A = 2.0 \frac{m}{s}
gauge pressure_A = 50 kPa
the view is from above, no height changes
find: gauge pressure @ B
so,
A_Av_A=2(A_Bv_B)
1.5*10^{-2}m^2(2.0\frac{m}{s})=2(5*10^{-3}m^2v_B)
v_B=9.0\frac{m}{s}
Bernoulli's equation (w/o...
Units for Speed Pertaining to Circular Motion
Hi,
So v=ω*r
Where v = velocity in m/s
ω = angular velocity in rad/s
r = radius in m
But I am confused...the units don't match! What happens to the rad?
m/s = (rad/s)*s
My textbook doesn't explain it, it simply does calculations...
