Determine the pump head (unit: meter or kPa), using the following parameters
Specify the sizes of pipes (cast iron, schedule 40) and the size of the motor to be used
for a pump to lift water at 40 Ips, from reservoir A to reservoir B.
Consider the following data:
Total static head
50 m
Fittings & valves;
Suction line
1 foot valve, 1 standard elbow, and 1 gate valve
1 check valve, 1 gate valve, 1 long sweep
elbow, and 2 standard elbows
Discharge line
Length of straight pipes:
Suction pipe
Discharge pipe
Absolute viscosity of water
Absolute roughness of cast iron
Darcy-Weisbach friction factor
Water velocity
300 m
80 m
0.001002 Pa-s
0.00026 m
0.025
1.0 m/s to 2.75 m/s
Neglect the head losses in the foot valve and at the pipe exit in the discharge
reservoir, and do not use equal sizes for the suction and discharge pipes.
Give the classification of flow meters.
