A certain fuid at 10 bar is contained in a cylinder behind a piston the initial volume being 0.05m. Calculate the work done by the fuld when it expends reversibly) At constant pressure to a final volume of 0.2 m. ii) According to a linear law to a final volume of 0.2m '. & a final pressure of 2 bar. iii) According to a law (PV - constant) to a final volume of 0.1 m IV) According to a law (P. V3 = constant) to a final volume or 0.063 V) According to a law (P = (A / V2) ) - (B / V)) to a final volume of 0.1 m & final pressure of l bar where A, B are constants. Sketch all processes on (p - v) diagram

A conical shaped tank of height H and width W is placed above a spherical water tank of radius R. Water drains from the conical tank into the spherical tank through a small opening of radius r. Similarly, the spherical tank empties though a small opening of radius r located at its bottom. Find the time it would take to drain both the tanks.

Imagine a space elevator with m = 30 kg/m extending from the surface (6400 km) to the geosynchronous height of 40,000 km. Take g to be changing with the height. If a stray satellite hits the top of the elevator find the time that the wave will take to reach the surface. The answer should be a few hours or so.
