NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
A piston–cylinder device contains 6 kg of H2 and 21 kg of N2 at 160 K and 5 MPa. Heat is now transferred to the device, and the mixture expands at constant pressure until the temperature rises to 200 K.
Determine the heat transfer during this process by treating the mixture as a nonideal gas and using Amagat’s law. The universal gas constant is Ru = 8.314 kPa·m3/kmol·K. Use the table containing the molar mass, gas constant, and critical-point properties; the generalized enthalpy departure chart; and the table containing the ideal-gas properties of air.
A 2.170-kg steam-water mixture at 1.0 MPa is contained in an inflexible tank. Heat is added until the pressure rises to 3.5 MPa and the temperature to 400°C. Determine the heat added in kJ.
Use steam tables of Keenan et al
A mixture of nitrogen and carbon dioxide has a carbon dioxide mass fraction of 50 percent. This mixture is heated at constant pressure
in a closed system from 120 kPa and 30°C to 220°C. Calculate the work produced during this heating in kJ/kg. The universal gas
constant is Ru= 8.314 kJ/kmol-K. Use the table containing the molar mass, gas constant, and critical-point properties.
The work produced during this heating is
kJ/kg.
