Solved: Energy Analysis of Control Volumes at Steady
Chapter 4, Problem 29P(choose chapter or problem)
Refrigerant 134 a flows at steady state through a horizontal pipe having an inside diameter of \(4 \mathrm{~cm}\), entering as saturated vapor at \(-8^{\circ} \mathrm{C}\) with a mass flow rate of \(17 \mathrm{~kg} / \mathrm{min}\). Refrigerant vapor exits at a pressure of 2 bar. If the heat transfer rate to the refrigerant is \(3.4 \mathrm{~kW}\), determine the exit temperature, in \({ }^{\circ} \mathrm{C}\), and the velocities at the inlet and exit, each in \(\mathrm{m} / \mathrm{s}\).

If the heat transfer rate to the refrigerant is \(3.4 \mathrm{~kW}\), determine the exit temperature, in \({ }^{\circ} \mathrm{C}\), and the velocities at the inlet and exit, each in \(\mathrm{m} / \mathrm{s}\).
ANSWER:Step 1 of 5
We have to find the exit temperature, inlet and exit velocities.
