Time left $0\mathrm{.}53$:$30$

for the steam power plant,

If you knowing the following

$h1=440k\frac{J}{k}g$

$h_2=480k\frac{J}{k}g$

$h_3=3010k\frac{J}{k}g$

$h_4=2620k\frac{J}{k}g$

$m=4k\frac{g}{s}$

find the following

$1--$ in $kW$

$2-$oout $[$kw$]$

$3-$Win $[$kw$]$

$4-$Wout $[$kW$]$

$5-$Efficency $\%$
