Springfield University has hired you to develop a web-based system to handle enrollment.
Here are Solution Domain Scenarios that describe one aspect of how the system will be
used:
Dean Peterson, the convenor for Introduction to Programming, wants to see which students
are enrolled in his unit. He browses to the Enrolment System site and logs in. As he is a
staff member, it shows him a list of all the units offered by the university. He scrolls down
to âIntroduction to Programmingâ and clicks on the title, which takes him to an information
page for the unit. Dean then clicks the âCurrent Enrollmentâ list and the system presents
him with a list of all the students currently enrolled in Introduction to Programming. Dean
scrolls down to the student Gary Benjamin and clicks his name. The system then shows him
Garyâs details.
Leopold is the convenor for Web Development. He logs into the Enrolment System,
brows

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
