A2: FLUID FLOW, FLOW RATE & PRESSURE DROPProblem:4. Determine the average velocity in m/s for water flow in a 2 in diameter pipe, Schedule 40 chlorinated polyvinyl chloride (CPVC) pipe (2.375 in outside diameter and 2.047 in inside diameter) carrying cold water at a volumetric flow rate of 40 gpm.
In a cast-iron piping system of 450 ft length shown below, the rate of flow
is 1 cfs at 70°F. Assuming the total head losses for the flow in the system is 10 ft,
what is the energy head supplied by the pump E?
a. 40 ft
b. 50 ft
c. 60 ft
d. 510 ft
e. None of the above
Water flows in a 100 mm (4 in.) commercial steel pipe at 15°C (59°F). If the center
velocity is 1 m/s (3.3 ft/s) what is the flowrate?
