The time required to close a valve gradually is >2L/C.
In this case, no water hammering condition produced means the pipe will be safe against bursting.
The time required to close a valve suddenly,t <=2L/C.
In this case, water hammering condition produced means the pipe will not be safe from bursting.

Nice, Thanks @Subha prakash.

2L/C is water hammer case if time of closure is less than it pipe will brust so for gradual closing time of closure should be greater than 2L/C.

wlv/gt(gradually closing).
wlkv/g(sudden closing).
Is right or wrong? Please tell me.
