Problem $08\mathrm{.}057-$ Mass flow rate and entropy generation during the process.

Liquid water at $200$ kPa and $15\backslash$deg C is heated in a chamber by mixing it with superheated steam at $200$ kPa and $150\backslash$deg C$.$

Liquid water enters the mixing chamber at a rate of $4\mathrm{.}3$k$($g$)/($s$),$ and the chamber is estimated to lose heat to the surrounding

air at $20\backslash$deg C at a rate of $1200$k$($J$)/($m$)$in$.$ The mixture leaves the mixing chamber at $200$ kPa and $80\backslash$deg C$.$ Use data from the

tables.

Problem $08\mathrm{.}057.$a $-$ Mass flow rate of the steam in a mixer

letermine the mass flow rate of the superheated steam. $($Round the final answer to four decimal places.$)$
