A wealthy and largely residential suburban area on the edge of a major city surrounded by small towns expands outward enormously every year, engulfing smaller communities and causing a ceaseless need for expanded road infrastructure to meet increased traffic demands. In an essay of between 150 and 250 words, describe the potential problems this expansion, if allowed to continue, could cause for the city and nearby communities, and what zoning could do to limit and control this expansion.

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
