Make your own or print a template online! Hint: The feasible region looks like this: Draw it carefully on the engineering paper! Then draw the objective function for a couple of values of the RHS, e. g. x + 2y = 3, x + 2y = 6. (a) What do you notice? Hint: The problem is unbounded, i. e. the objective function can be made to go to infinity! Attach solution ON ENGINEERING PAPER! 2] Sec. 10.1 – Prob.5(b): Apply the Simplex algorith

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

Aquick transition of the operating speed of a shaft from its critical speed will whirl amplitude. (a) increase (b) limit (c) not affect (d) zero

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
