Problem Statement

Water at $\backslash (25^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$ and $140$ bar enters a boiler at a flowrate of $\backslash (0\mathrm{.}1\backslash$mathrm$\{$~kg$\}/\backslash$mathrm$\{$s$\}\backslash ).$ It exits the boiler and enters a nozzle to produce a high$-$velocity jet of saturated vapour to be used for cleaning purposes. The process in the nozzle can be described by $\backslash ($ P v$^\{1\mathrm{.}1\}=\backslash )$ constant. The pressure at the exit of the nozzle is $1$ bar. At what rate must heat must be supplied to the boiler? What is the velocity at the exit of the nozzle?
