Question six

Water flows through a pipeline $600m$ long between two reservoirs which have a difference in elevation of the water surface of $50m$ At mid$-$point the pipe suddenly double from $150mm$ to $300mm$ in diameter. The entrance and exit are both guidden. The friction factor :$=0\mathrm{.}04$

a List the losses of head that occur giving an expression for each $(15$ marks$)$

b$)$ Determine the flow rate $(5$ marks$)$
