Q1:

Hydraulic gradient is equal to difference in water surfaces

A

B

C

D

ANS:B -

Answer A because friction loss will only when fluid is in motion. In both cases either in rest or in motion there will be diff in surfaces which is total head loss including friction.

I=head loss/L head loss may be due to pressure head/velocity head/datum head/friction or combination of these
