Energy Analysis of Control Volumes at Steady StateAn open

Chapter 4, Problem 81P

(choose chapter or problem)

An open feedwater heater operates at steady state with liquid water entering inlet 1 at \(10 \mathrm{bar}, 50^{\circ} \mathrm{C}\), and a mass flow rate of \(60 \mathrm{~kg} / \mathrm{s}\). A separate stream of steam enters inlet 2 at 10 bar and \(200^{\circ} \mathrm{C}\). Saturated liquid at 10 bar exits the feedwater heater at exit 3 . Ignoring heat transfer with the surroundings and neglecting kinetic and potential energy effects, determine the mass flow rate, in \(\mathrm{kg} / \mathrm{s}\), of the steam at inlet 2.
