100
Determine velocity in ft/sec if flow through a 10" pipe is 722 GPM.
100
Standardized safety practices of lockout/tagout are used to disable _____ to prevent ______ during maintenance activities.
What is:

200
Find the total head, in feet, for a pump with a total static head of 19 ft and a head loss of 3.7 ft.
What is 22.7'?
Total Head = Static Head + Losses
Total Head = 19 ft + 3.7 ft
Total Head = 22.7 ft
