(1) 2 kg/s оf sаturаted vаpоr steam at 3 MPa is cоndensed in a steady-flow heat exchanger to saturated liquid as shown below. The heat removed from this stream is absorbed by a cooling water stream which enters at 0.1 MPa and 20 oC. It is desirable that no vapor forms in the cooling water stream. What is the minimum cooling water flow rate (kg/s) for which the cooling water will remain liquid throughout the exchanger? (2) A closed, rigid, insulated vessel contains H2O at 0.4 MPa with a quality of 35%. A stirrer is activated and supplies work to the H2O until the pressure is 0.8 MPa. The amount of work is observed to be 200kJ. How many kg of liquid turn to vapor during this process? (3) A rigid vessel is connected to a liquid water supply line as shown below. Initially, the vessel contains saturated steam at 0.1 MPa. The valve connecting the vessel to the water line is opened and 1.6 kg of water from the line is added to the vessel. At the same time, heat is added to the vessel. The filling is slow enough and the pipeline is large enough that the properties of the water in the pipeline remain constant during the filling. The final state in the vessel is saturated vapor. (a) What is the final pressure (MPa) in the vessel? (b) How much heat (kJ) was added to the vessel?
