![1. 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 50 from reservoir A to reservoir B.
Consider the following data:
Total static head
Fittings and valves:
Suction line
Discharge line
Length of straight pipe:
Suction pipe
Discharge pipe
Absolute viscosity of water
Absolute roughness of cast iron
Water velocity
50 m
1 foot valve, 1 standard elbow
1 gate valve
1 check valve (same as close
return valve), 1 gate valve,
1 long sweep elbow,
2 standard elbow

80 m
0.001002 Pa-s
0.00026 m
m
1.18 -2.75
S
Pump efficiency

Note: Neglect the head loss in the foot valve and at the pipe exit in the discharge reservoir
and do not equal sizes for the suction and discharge pipes. Draw the piping system.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbb96304d-6c7c-4387-a303-381418b4891a%2Ff35118ff-2ebc-408f-b942-c156cc5354a8%2F88jbcns_processed.jpeg&w=3840&q=75)
