Question

Problem # 1 A 1 m³ tank contains 3.5 kg of steam ($H_2O$). 1) At pressure of 775 kPa, determine the temperature of the steam, using (a) the ideal gas equation, (b) the steam tables. Calculate the error percentage in using ideal gas assumption. 2) Determine the temperature in part (1) but now consider the pressures of 0.1 MPa and 1 MPa. Comment on the values.

          Problem # 1
A 1 m³ tank contains 3.5 kg of steam ($H_2O$).
1) At pressure of 775 kPa, determine the temperature of the steam, using (a) the ideal gas
equation, (b) the steam tables. Calculate the error percentage in using ideal gas
assumption.

Step 1

The ideal gas equation is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature. First, we need to convert the mass of steam to moles. The molar mass of water is approximately 18 g/mol, so Show more…
