Technician A says that the basecoat may be applied directly over a self-etching primer. Technician B says that the acid in self-etching primer neutralizes as it dries. Who is right

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

Inadequate stores control is not an obstacle to effective work order system. (clo4) a)-true b)-false
