Question
A farmer has set up a piping system (shown below) to move water from one irrigation pond to
another. The system includes two standard 90 ° elbow and a grate valve. When the valve is
open to the system should maintain a flowrate of 100 gallons/min. The pipes are made of
commercial steel and have a diameter of 4” (inches). The density and viscosity of the water (60
°F) are 62.3 lbm/ft3 and 0.76 × 10 ―3 lbm/ft s. There is no change in height across the system
and you are looking at the top view below.
