Nitrogen is steadily compressed from 112 kPa and 12 C to 571 kPa and 226 C. It is estimated that 20.3 kJ/kg of heat is exchanged with the surrounding air while maintained at a constant 25C during the process. Determine the entropy generated during this process in kJ/kg/K.

On a average work day more than work place firs are reorted

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges
