Two air flows are combined to a single flow. One flow is $1\mathrm{.}5($m$^(3))/($s$)$ at $35\backslash$deg C and the other is $2\mathrm{.}52($m$^(3))/($s$)$

at $252\backslash$deg C$,$ both at $110$ kPa $,$ as in Fig$\mathrm{.}3.$ They mix without any heat transfer to produce an exit flow at

$101$kPa. Neglect kinetic energies and find the exit temperature and volume flow rate.
