Task id10375
A vertical pipe with a piston tightly adjacent to its inner walls is lowered with its lower end into water. Initially, the piston was in the lowest position, at the water level, and then it was slowly raised to a height of 20 m. Neglecting friction, find the work done (in kJ). Piston area 100 cm2. Atmospheric pressure 100 kPa. g = 10 m/s2.
