Assume that each pair is in a random order, and that the pairs are in random order. The GENERAL EXAMPLE is a possible order. What is the exact number of comparisons in the average case as a function of n?

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

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false

The quality is zero at a)-the saturated vapour state b)-the saturated liquid state c)-the saturated liquid-vapour mixture state d)-none of the states in the other answers
