Technician A states that when measuring the drum diameter, the measurement should be taken at the deepest groove or worn part of the drum. Technician B states that if it is over the size limit, the drum must be replaced. Who is correct?

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

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

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
