Q$4$: $[20$ points$]$

$2\mathrm{.}15.$ The control volume shown in Figure P$2\mathrm{.}15$ has steady, incompressible flow, and all

properties are uniform at the inlet and outlet. For $u_1=1\mathrm{.}256M\frac{J}{k}g$ and $u_2=1\mathrm{.}340$

$M\frac{J}{k}g$ and $=10k\frac{g}{m^3},$ calculate the work if there is a heat output of $0\mathrm{.}35M\frac{J}{k}g.$

$z_2=20m$

$V_2=70\frac{m}{s}$

$p_2=1{10}^5\frac{N}{m^2}$

$z_1=0$

$V_1=10\frac{m}{s}$

$p_1=1\mathrm{.}3{10}^5\frac{N}{m^2}$
