Assume a future where security countermeasures against DoS attacks are much more widely implemented than at present, ln this future network, antispoofing and directed broadcast filters are widely deployed. Also, the security of PCs and workstations is much greater. making the creation of hot nets difficult. Do the administrators of server systems still have to be concerned about, and take further countermeasures against. DoS attacks? It so. what types of attacks can still occur, and what measures can be taken to reduce their impact?

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
