Because each pipe is impose some friction force. Which is slow down the flow of the liquid at each part of the series of pipe.

What is head loss?

Neeraj said: (Jan 15, 2017)  
Head is an available amount of energy which gives a potential energy or impulse momentum to turbine or any moving device if head loss or total head reduce so energy is reduced, the total energy is head form p/ρg +V2/2G+z.

What happens if they are parallel?

It is same in each pipe.

The correct Option is A.

Series systems " the flow rate through the entire system remains constant, the total head loss, this case is equal to the sum of the head losses in individual pipes, parallel pipe system " head loss is the same in each pipe, and the total flow rate is the sum of the flow rates in individual pipes.

When pipes are connected in series:
Q = Q1 = Q2 = Q3.
H = H1+H2+H3.

When pipes are in parallel:
H = H1 + H2 + H3.
Q = Q1 + Q2 + Q3.
