| In a certain device using water as the working fluid, superheated vapor at state 1 flows in, liquid at state 2 flows n, and saturated vapor at state 3 flows out. Ignoring stray heat transfer and kinetic and potential energy effects. Data are provided as follows: State 1: superheated vapor, temperature is 200 °C, pressure is 5 bar. State 2: liquid, temperature is 20 °C, pressure is 5 bar, mass flow rate is 7.07 kg/min. State 3: saturated vapor, pressure is 5 bar. Determine the mass flow rate of the incoming superheated vapor, in kg/min. Determine thc mass flow rate of the outgoing saturated vapor, in kg/min. a.

5Air enters a two-stage compressor operating at steady state at 520°R, 14 lbf/in.2 The overall pressure ratio across the stages is 12 and each stage operates isentropically. Intercooling occurs at constant pressure at the value that minimizes compressor work input, with air exiting the intercooler at 520°R. When the temperature of the air entering each compressor stage is the same, the minimum total compressor work input per unit of mass flowing occurs when the pressure ratio is the same across each stage.Assuming ideal gas behavior, with k = 1.4, determine the work per unit mass of air flowing for the two-stage compressor, in Btu per lb of air flowing.

Handwritten answer needed.
Air enters a two-stage compressor operating at steady state at 520°R, 14 Ibf/in.2 The overall pressure ratio across the stages is 16 and each stage operates isentropically. Intercooling occurs at constant pressure at the value that minimizes compressor work input, with air exiting the intercooler at 520°R. When the temperature of the air entering each compressor stage is the same, the minimum total compressor work input per unit of mass flowing occurs when the pressure ratio is the same across each stage. Assuming ideal gas behavior, with k = 1.4, determine the work per unit mass of air flowing for the two-stage compressor, in Btu per Ib of air flowing. W. Btu/lb m
