Q1:

While deriving an expression for loss of head due to a sudden expansion in a pipe, in addition to the continuity and impulse-momentum equations, one of the following assumptions is made :

A Head loss due to friction is equal to the head loss in eddying motion

B The mean pressure in eddying fluid is equal to the downstream pressure

C The mean pressure in eddying fluid is equal to the upstream pressure

D Head lost in eddies is neglected

ANS:C - The mean pressure in eddying fluid is equal to the upstream pressure
