DWizzleWolf Posted June 13, 2014 Share Posted June 13, 2014 Ok so I have a bunch of questions that I need help with so I am just going to make one big post, all the help I can get is appreciated!!! 1) A cylinder contains 3.0 kg of a water mixture that is in two phase equilibrium at a pressure of 500 kN/m2. If the volume of the cylinder is 1.0 m3, determine the following: a) Temperature of the mixture in the initial equiulibrium. b) Volume and mass of liquid water. c) Volume and mass of vapor 2) A cylinder has a volume of 0.2 m3 of O2 at 70 C and 25.0 bars. Calculate the amount of O2 in the container if the atmospheric pressure is 1.0 bar. 3) Calculate the work necessary to compress air in an insulated cylinder from a volume of 2.0 m3 to a volume of 0.2 m3. The initial temperature and pressure are 20 C and 200 kPa, repectively. Thanks! Link to comment Share on other sites More sharing options...
studiot Posted June 13, 2014 Share Posted June 13, 2014 So what have you achieved so far, and have you read the rules of homework help? http://www.scienceforums.net/topic/75772-read-this-before-posting-in-homework-help/ Don't forget to convert temperatures to absolute before doing any calculations.
