A turbine with $\%90$ efficiency is inserted in

the pipeline. If the flow rate is $2\mathrm{.}1\frac{m^3}{s}$ and

$f=0\mathrm{.}021$ for the concrete pipe, calculate the

turbine power output. $($Assume the minor losses

can be ignored.$)$

a$)3\mathrm{.}22MW$

b$)2\mathrm{.}54MW$

c$)1\mathrm{.}05MW$

d$)0\mathrm{.}76MW$

e$)1\mathrm{.}65MW$
