You have learned so much about coding throughout the past six units! Looking back on everything, which elements of code are you now comfortable with and why? On the flip side, which elements have proven to be the most challenging? Explain your answer. And finally, if you want to keep developing your coding skills beyond this course, where might you look for extra practice?

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
