a mixing chamber has 2 inlets, first, steam water enters at 12 bar and 1173.15 K , then, saturated liquid enters at 12 bar and 80 kg/min. The exit conditions are 12 bar and 120 kg/min. Obtain the mass flow rate (kg/s) at which steam water enters, the temperature at the exit (C°) and the quality of substance at the exit. Ignore the changes of kinetic and potencial energy.

Consider a mixing chamber where two separate streams of fluid mix and then exit as a single stream. One of the stream that enters the mixing chamber is superheated steam at 5 bar and 2000C. The other stream that enters the mixing chamber is a liquid water at 5 bars and 400C. The two streams mix in the mixing chamber and exit as a single stream. The single stream that exits is saturated liquid at 5 bar. Determine the ratio...

Liquid water at 293 K and 1.8 kg/s is mixed with steam at 573K in a heating chamber. The water leaves the chamber at 300 kPa and 333K. Determine the mass flow rate of the steam. Where it exists in such a state, you may assume compressed liquid to have the same properties as saturated liquid at that temperature.

Steam enters a horizontal 14-cm-diameter pipe as a saturated vapor at 5 bar with a velocity of 10 m/s and exits at 4.5 bar with a quality of 95%. Heat transfer from the pipe to the surroundings at 291K takes place at an average outer surface temperature of 400 K. For operation at steady state, determine (a) the velocity at the exit, in m/s. (b) the rate of heat transfer from the pipe, in kW.? (c) the rate of entropy...

Two products enter an indirect contact heat exchanger that uses steam for heating. The first product which contains 15% solids enters at the rate of 3 kg/hr and at 10 °C. The second stream which contains 20% solids enters at the rate of 4 kg/hr and at 20 °C. Saturated steam at 140 °C enters the heat exchanger at 0.5 kg/hr with a quality of 95% and exits at 10% quality at 140 °C. The resulting mixture enters an indirect...

13)  A turbine, operating under steady-flow conditions, receives 5000 kg of steam per hour. The steam enters the turbine at a velocity of 3000 m/min, an elevation of 5 m and a specific enthalpy of 2787 kJ/kg. It leaves the turbine at a velocity of 6000 m/min, an elevation of 1 m and a specific enthalpy of 2259 kJ/kg. Heat losses from the turbine to the surroundings amount to 16736 kJ/h. Determine the power output of the turbine. 14) 12 kg...

Mixture of saturated liquid-vapor water enters a compressor with mass flow rate of 2 kg/s, velocity of 150 m/s, pressure of 10 kpa and quality of 0.85. The substance leaves the compressor with the velocity of 40 m/s at 7 MPa and 450°C. The heat loss from the compressor is 200 kW. Neglecting the changes in potential energy, determine the compressor required power.
