Document Summary
Properties of pure substances: for a specific volume of 0. 2 m3/kg, find the quality of steam if the absolute pressure is (a) 40 kpa and ( b )6 30 kpa. What is the temperature of each case: calculate the specific volume of water at ( a ) 160"c and ( b )221 c if the quality is 85 percent. Ten lb of steam is contained in a volume of 50 ft3. Find the quality and the pressure if the temperature is 263of: a tank is filled with oil whose density is r _ 850 kg/m3. The tank is located on a mountain at an altitude of. 1400 m where the atmospheric pressure is 85. 6kpa. Does this violate the conservation of energy principle: an office worker claims that a cup of cold coffee on his table warmed up to 80 c by picking up energy from the surrounding air, which is at 25 c.
