(tco 6) consider a demand-paging system in which a process is allocated six frames. let the least recently used (lru) algorithm be employed to select pages for replacement. let the sequence of page references for the process be as follows: 1, 3, 4, 1, 5, 2, 3, 8, 6, 7, 10, 3, 9, 4, 3, 8, 5, 1, 2, 5, 3, 1, 7, 5, 1, 2 at the end of processing the above sequence of references, determine the set of pages resident in memory. now, identify the page reference from the following that will cause a page fault.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented
