A 1.10-m length of horizontal pipe has a radius of 4.77 cm. Waterflows with a volume flow rate of 5.86 x 10-3 m3/s out of the rightend of the pipe and into the air. What is the pressure in theflowing water at the left end of the pipe if the water behaves as(a) an ideal fluid and (b) a viscous fluid ? = 1.00 x 10-3Pa·s)?
I get that part A is normal atmospheric pressure 1.013 x 10^5
For part B I keep getting the wrong answer when I use Poiseuille'slaw I get : 101303.1723 Pa which is wrong.
