Air enters the rotor of an axial compressible stage with an axial velocity of 150 m/s and a tangential component of 80 m/s. The average rotor blade speed is 250 m/s. The blade angles are 48 degrees at the rotor inlet and 28 degrees at the rotor outlet (25 pts) a) Assuming the axial velocity component remains unchanged through the rotor passage, what is the change in tangential velocity ( C ) through the rotor passage

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
