2. Determine the volume occupied by a 2kg steam at 500kPa, under the following conditions:
(a) pressure state
(b) pure vapor state
(c) 20% moisture content
(d) 20% dry
When P (kPa) = 500, T (°C) = 151.86, Vf (m³/kg) = 0.0019 and Vg (m³/kg) = 0.3749
3. An automobile tire contains a certain volume of air at 205kPa, and 20°C. The barometric pressure is 100kPa, if due to maintaining conditions the temperature of the air in the tire rises to 70°C, what will be the gage pressure? Assume that the air is an ideal gas and that the tire does not stretch.
