1. Let's do a re-mix of Problem 1 from HW2. The figure from HW2 was: Let's talk about heat instead of a chemical contaminant. Given: --The stream of interest has

a flow rate of a_{s}=15 \mathrm{~m}^{3} / \mathrm{s} --The temperature of the stream T, is 15 °C. --A heat waste discharge flow of a_{w}=0.5 \mathrm{~m}^{3} / \mathrm{s} carrying a temperature of T_{w}=35^{\circ} \mathrm{C} Is instantaneously mixed in the stream. Using the same general approach as in HW2 problem 1, but for enthalpy concentration, what is the temperature after mixing?
