The loss of head due to an obstruction is dependent on the cross-section of the obstruction, So it is not fixed and has a dependency on the cross-section of pipe and the cross-section of obstruction.
Head loss = V sq /2g *(A/((A-a)*Coefficient of cont.)-1) sq.
A = area of the pipe.
a = area of obstruction.
Head loss = V sq /2g *(A/((A-a)*Coefficient of cont.)-1) sq.
A = area of the pipe.
a = area of obstruction.

Loss of head at entrance = 0.5 V sq/2g.
Loss of head due to obstruction = V sq/2g.
Loss of head due to obstruction = V sq/2g.
