# Really stuck on Poiseuille's Law and rate of flow word problem?? Calculus/physics, please explain and help?!?

Poiseuille's Law gives the rate of flow,R, of a gas through a cylindrical pipe in terms of the radius of the pipe,r, for a fixed drop in pressure between the two ends of the pipe

Poiseuille's Law gives the rate of flow,R, of a gas through a cylindrical pipe in terms of the radius of the pipe,r, for a fixed drop in pressure between the two ends of the pipe

(a) Find a formula for Poiseuille's Law, given that the rate of flow is proportional to the fourth power of the radius. (Use k for any constant of proportionality you may have in your equation.)

R=_____________________

(b) If R=430 cm3/s in a pipe of radius 2 cm for a certain gas, find a formula for the rate of flow of that gas through a pipe of radius r cm

R=_______________________

(c) What is the rate of flow of the same gas through a pipe with a 5 cm radius?

R=__________________________
