Chapter 4, Problem 4.71P

A mixing chamber with heat transfer receives $\text{2 kg}/\text{s}$ of $\text{R}-\text{410A}$ , at $\text{1 MPa 4}0°\text{C}$ in one line and $\text{1 kg}/\text{s}$ of $\text{R}-\text{ 41}0\text{A}$ , at 15°C with a quality of $\text{5}0\%$ in a line with a valve. The outgoing flow is at $\text{1 MPa},\text{ 6}0°\text{C}$ . Find the rate of heat transfer to the mixing chamber.
