A pressure difference of 600 x 104 pa is required to, Ask an Expert

Academics

A pressure difference of 6.00 x 10^4 Pa is required to maintain a volume flow rate of 0.800 m^3/s for a viscous fluid flowing through a section of cylindrical pipe that has radius 0.180m .

What pressure difference is required to maintain the same volume flow rate if the radius of the pipe is decreased to 0.0900m?
