Saturated water vapor enters the turbine at 15 bars (state 3) and leaves at 0.7 bar with a quality of 83.5411 percent (state 4, use this number with all given decimals). the fluid leaves the condenser as a mixture of vapor-liquid with 17.8616 percent quality ( use this number with all given decimals) at 0.7 bar (state 1). state 2 is a saturated liquid at 15 bars. assuming it is a continuous cycle, turbine and pump are adiabatic, it has a steady state flow and kinetic energy change and potential energy change are negligible. determine

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?

The process in which the system pressure remain constant is called a)-isobaric b)-isochoric c)-isolated d)-isothermal
