In the city water tower, water is pumped up to a level
25mabove the ground in a pressurized tank with air at 125 kpa over
thewater surface. assuming a water density of 1000
kg/m3and standard gravity, find the pressure required to
pump more waterin at ground level.

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

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
