Homework Statement
Water is flowing through a horizontal pipe that has a radius of 6 cm gradually narrowing to a
radius of 4 cm. The volume flow rate is 0.008 m3/s. What is the difference in the water pressurebetween the 6 cm radius region and the 4 cm radius region of the pipe?
Homework Equations
P + .5pv^2 + pgy = constant
The Attempt at a Solution
y is 0 so that part cancels
p(density) is 1000 kg/m^3 for water
P1 + .5pv1^2 = P2 + .5pv2^2
