I used the formula for flow rate: which is

Q = (pi)r^4(delta Pressure) / 8(coefficient of viscosity)(length)

I converted the diameter of 1.0 cm to .005 Meters radius, and the rest of the information is given

9.0 x 10^-5 = pi(6.25 x 10^-10)(Change in pressure) / 8(0.12)(50)

When i solve for pressure i get 21.7192 atm, and final pressure is 1,

so initial pressure is 1 + 21.7192 atm, which is 22.7192 ATM which is 2.30145 x 10^6 pascals

do you guys see anything wrong? thanks
