consider the following system number of pages 2k page size is 4k words physical address 18 bits now calculate logical address space and number of frames?

A certain fluid of 10 bar is contained in a cylinder behind a piston, the initial volume being 0.05m³. Calculate the work done by the fluid when it expands reversibly according to the linear law to a final volume of 0.2m³ and a final pressure of 2 bars.

A glulam beam is manufactured with a depth of 16 in. and a 8% moisture content. Assuming common

values for estimating dimensional changes, compute the new depth of the beam if the moisture content is increased to 40%. (The fiber saturation point is 39%, and it shrinks 6.53% in drying from FSP to oven dry in the tangential direction.)

A 370-mm wide plank is cut in such a way that the width is in the tangential direction of annual rings.

Compute the change in width as the moisture content changes from 18% to 42%. (The fiber saturation point is 35%, and it shrinks 8.21% in drying from FSP to oven dry in the tangential direction.)
