Africtionless bison cylinder device contains 10kg of water at 20 degrees c at atmospheric pressure. an external force f is then applied on the piston until the pressure inside the cylinder increases to 100 atm. assuming the coefficient of compressibility of water remains unchanged during the compression; estimate the energy needed to compress the water isothermally.

Most leaks in reciprocating air compressors can be detected and minimized by: (clo4) a)-detecting leakage areas using ultrasonic acoustic detector. b)-tightening joints and connections c)-replacing faulty equipment d)-all of the given options

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
