Two moist air streams mix adiabatically $($without condensation$).$ Stream $1$ is characterized by $h_1=90k\frac{J}{k}g$ and ${}_1=20\frac{g}{k}g$ and $m_1^{}=1000k\frac{g}{s}.$ Stream $2$ is characterized by $h_2=50k\frac{J}{k}g$ and ${}_2=8\frac{g}{k}g.$ The exit stream has an enthalpy of $60k\frac{J}{k}g.$

Note: Show the process on the attached psychrometric chart.

a$.$ Determine the dry bulb temperature of the exiting mixture

b$.$ Determine the wet bulb temperature of the exiting mixture

c$.$ Determine the mass flow rate of stream $1m_1^{}$ and stream $2m_2^{}.$ Show the process on the attached psychrometric chart.

d$.$ Determine the dew point temperature of the exiting mixture
