A piston-cylinder device fitted with stops as shown in the figure initially contains one kg of water at 400 kPa and 300°C. Heat is rejected from the cylinder at constant pressure until water exists in the cylinder as a saturated vapour and the piston rests on the stops. Heat rejection from the cylinder continues until the pressure is 100 kPa. Calculate the dryness fraction at the end of process.
1 A two-phase liquid-vapour mixture of water, initially at a pressure of 5 bar and dryness fraction of 0.5, is heated in a closed rigid tank of volume 0.2 m3 until only saturated water vapour remains. The approximate mass of the water and the final pressure will be respectively
1.064 kg, 10.5 bar
2.064 kg, 10.5 bar
1.064 kg, 1.5 bar
2.064 kg, 1.5 bar

Perform an analysis for disk ranges from 0 to 199 for the following sequence of disk tracks requests: 127, 12, 110, 92, 147, 141, 10, 14, 83, 188, 25 and 120. Assume disk head initially at track 100 and is moving in the direction of decreasing track number. Perform the analysis on FIFO, SSTF, SCAN, and CSCAN algorithms. Calculate the total head mowvement for each algorithm and represent with graph.
Find the shortest length L for a steel column with pinned ends having a cross sectional area of 60 x 100 mm, for which the elastic euler formula applies. Let E= 200 GPa and assume proportional limit to be 250MPa.
use the graphical method to find out the following for a state of pure shear having magnitude equal to 30 k N / m square:
a) principal stresses and principle plane
b) planes of maximum shear
c) normal and shear stress on plane of maximum shear
d) stress on a plane inclined at an angle of 30 degree anticlockwise with the vertical plane
An electromechanical voltmeter ( range 0-100V) with zero error after calibration has a pointer bias of + 0.5V ( due to transportation). a) If the voltmeter reads 80V what is the absolute error (if such), of measurement with the voltmeter? b)What are the realtive and reduced errors ( if such)?
