It is to think in terms of two basic kinds of change: piecemeal and systemic. piecemeal change leaves the structure of a system unchanged. it often involves finding better ways to meet the same needs, such as using an analogy to your students learn the science concepts you taught in an otherwise similar manner last year. in contrast, systemic change entails modifying the structure of a system, usually in response to new needs. references: reigeluth, c. m. (1999). what is instructional-design theory and how is it changing?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

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
