c) What are the qualities x for saturated liquid and saturated vapor, respectively?
. Calculate the molar volume of saturated liquid and the molar volume of saturated vapor by the Redlich / Kwong equation for Propane at 400C (313.15 K) where P sat = 13.71 bar and compare results with values found by suitable generalized correlations. (Ans. For saturated liquid: Z= 0.057; V = 108.1 cm3/mol; For saturated vapor: Z= 0.789; V = 1499.2 cm3/mol)

Problem Statement This assignment should be completed in self-selected groups of 2-3 students. You and your teammates will construct a Concept Map that clearly illustrates how to use the "steam tables" (A-4 through A-7 in SI units) to find the thermodynamic properties and/or determine the phase of water Your maps should include the following concepts (at a minimum): All 5 phases discussed in...

A 200-m' rigid tank is filled with saturated liquid-vapor mixture of water at 50°C. If 10% of the mass is liquid and the rest is vapor, find the total mass in the tank. If heat is added in and the mixture becomes saturated vapor, find the pressure.
Can saturated water vapor at 200 kPa be condensed to a saturated liquid in an isobaric, closed system process while only exchanging heat with an isothermal energy reservoir at 90 C? (Hint: Determine the entropy generation.) please include given and schematic please
In a vapor-compression refrigeration cycle, ammonia exits the
evaporator as saturated vapor at -22 °C. There are
irreversibilities in the compressor. The refrigerant enters the
condenser at 16 bar and 160 °C, and saturated liquid exits at 16
bar. There is no significant heat transfer between the compressor
and its surroundings, and the refrigerant passes through the
evaporator with a negligible change in pressure.
Calculate the coefficient of performance, b, and the isentropic
compressor efficiency, defined as:
2s Condenser Expansion...
An insulated rigid vessel contains 5kg of saturated liquid-vapor mixture of Refrigerant- 134a at 200kPa. At this stage, one-fifth of the mass is in vapor phase and rest is in liquid. Now using an electrical resistance heater, heat is supplied to the contents of the vessel until all of the refrigerant is converted to saturated vapor. Show this process on a P v diagram with respect to saturation lines and determine, 1. volume of the rigid vessel 2. temperature, in...
Problem 4 Saturated water vapor at 150 kPa is condensed to saturated liquid in a steady-flow, isobaric heat exchanger. The released heat is transferred to the surrounding air whose temperature is at 20°C Determine the total entropy generation per unit mass associated with this process.
