# Fluid Dynamic and Flow Rate

Not what you're looking for?

A horizontal water main with a cross-sectional area of 200 cm^2 necks down to a pipe of area 50 cm^2. Meters mounted in the flow on each side of the transition coupling show a change in gauge pressure of 80 kPa. Determine the flow rate through the system, taking the fluid to be ideal.
