WebA gas sample is confined within a chamber that has a movable piston. A small load is placed on the piston; and the system is allowed to reach equilibrium. If the total weight of the piston and load is 70.0 N and the piston has an area of 5.0 × 10-4 m2, what is the pressure exerted on the piston by the gas? WebHAUG.Pluto oil-free and gas-tight compressors (0.5 - 2.2 kW) The HAUG.Pluto range is used for gas recovery and booster compression of gases such as helium, SF6, oxygen and nitrogen, as well as for booster compression (boosting) of compressed air. HAUG.Pluto compressors have the electric motor in the gas compartment.
