Select the best answer and write your answer in the table for the questions $(10-13)(8$ marks$)$

$-$Water has density $1000kg{m}^{-3}$ flows from elevated reservoir through a conducted turbine $($efficiency

$-10056)$ at a lower level and out of the turbine through a pipe. At a point $100$ m above the turbine the

pressure is$.200$ kpa $,$ the pressure

after the turbine is $100$ kPa $.$ The

turbine connected with a generator

has an efficiency $95\mathrm{.}20\%,$ the

electrical power output of the

generator is $0\mathrm{.}952$ MW at rotation

speed $3000$ rpm$,$ consider that the

gravitational acceleration $g=10$

$\frac{m}{s}\frac{?}{2}.$ The generator connected

with clectrolyzer has efficiency $75\%$

to generate hydrogen has heating

value $39\mathrm{.}4kW\frac{h}{k}g.$ solve the

following questions $(10-12)$:

The water mass flow rate

pequired in $\frac{m^3}{s}.$

$($A$)0\mathrm{.}91$

B$.{1\mathrm{.}64}^{-}$

C$.2\mathrm{.}13$

D$.10\mathrm{.}32$

E$.$ all of the answers are not correct
