Saturated liquid at 160°C is contained in a closed rigid vessel. The vessel is heated until the pressure is 2500 kpa. Compute of the change of entropy in kj/k if the mass of liquid is 30.60 kg
Carbon dioxide flows steadily through a varying cross-sectional area duct such as a nozzle shown in fig at a mass flow rate of 3.00 kg/s. The carbon dioxide enters the duct at a pressure of 1400 kPa and 200°C with a low velocity, and it expands in the nozzle to an exit pressure of 200 kPa. The duct is designed so that the flow can be approximated as isentropic. Determine the density, velocity, flow area, and Mach number at each location along the duct that corresponds to an overall pressure drop of 200 kPa.
For the specific volume of wet steam, SV=(1-Xv)SV (liq) + XvSV (vapor). Entropy is also calculated this way. If a tank initially has 5kg of wet steam with mass of vapor =1 kg at 100 kPa, and it is heated such that saturated vapor remains in the tank. Assuming that the process is in constant volume, what will be the entropy change of the steam (Kj/K)?
