Afilter manufacturer intends to establish a component acceptance criterion that is based upon sound statistical methods. preliminary tests conducted on 41 samples have determined that the mean diameter of the printer is 10.5 mm with a standard deviation is 0.55 mm. an estimate, with 95 % confidence, of the value of the next (42) measured load to produce failure.

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
