A 1m³ tank contains 2.841 kg of steam at 0.6 MPa. Determine the temperature of the steam, using (a) the ideal gas equation, (b) the van der Waals equation, and (c) the steam tables. Then, (d) calculate the compressibility factor.

R-134a at 1.4 MPa has a specific volume of 0.02000 m³/kg. Determine the temperature of the R-134a based on: (a) The tables of data, (b) The ideal gas equation of state, and (c) The generalized compressibility chart. (d) Compare the result in (b) to the result in (a) and determine the percentage error. (e) Compare the result in (c) to the results in (a) and determine the percentage error.

A real gas exists at 130 C and 1.2 MPa. It is known that the critical temperature and critical pressure of the gas is 374.2 k and 4.059 MPa. It is also know that the ideal gas constant (R) of the gas is 0.12 kPa-m/ S/kg-K. In the question that follows, select the answer that is closest to the true value. Use the compressibility factor (Z) to determine the specific volume in units of m/kg. ,3, Tuesday Dece mber 7 2021 5:52:58 DM CST
