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

The ivanpah solar thermal power plant cost $2.2 billion to build. the gross plant electric output is 392 mw, and the net output is 377 mw. the planned capacity factor was 27.4%, but the actual capacity factor in 2016 was 20.5%. at best the plant thermal efficiency appears to be 18%. in addition, for the daily startup process, the solar plant also burned 1.3x10^12 btu of natural gas in 2016. the cost of natural gas in 2016 was about $2.5 per million btu. assuming a levelized annual fixed charge rate of 7%, determine (a) the capital cost (c/kwh) and (b) the fuel cost (e/k wh) for the electricity in 2016.
