A rigid tank with a total volume of 0.8m3 initially contains
water in the form of a saturated liquid-vapour mixture at
P1=500kPa. The liquid portion of the mixture initially occupies a
volume of only 0.5L (the remainder is vapour). Steam from a supply
line at Pi=1000kPa and Ti=500°C is then injected into the tank
until the pressure in the tank reaches P2=800kPa. At this point
(final state), the mass in the tank is m2=2.8kg.

Thermodynamics 1. (correct answer: 0.080595 ) Initially, an insulated rigid tank contains 20 kg of water at 29.5oC and 101 kPa. The tank also contains a 4.86 kg aluminum block at 93.2oC. Using constant specific heats evaluated at 300 K, determine the total entropy production (kJ/K) after an hour assuming thermal equilibrium is achieved. 2. Correct Answer: 8.0087 ± 0.1% Steam at 1 MPa, 593.2oC, expands in a turbine to 0.01 MPa. If the process is isentropic, find the specific...
A 1.8-m3 rigid tank contains steam at 220°С
A 1.8-m3 rigid tank contains steam at 220°С. One-third of the volume is in the liquid phase and the rest is in the vapor form. Determine (a) the pressure of the steam, (b) the quality of the saturated mixture, and (c) the density of the mixture.
A well-insulated rigid tank contains 2 kg of a saturated liquid-vapor mixture of water at 100 kPa
A well-insulated rigid tank contains 2 kg of a saturated liquid-vapor mixture of water at 100 kPa. Initially, three-quarters of the mass is in the liquid phase. An electric resistance heater placed in the tank is now turned on and kept on until all the liquid in the tank is vaporized. Determine the entropy change of the steam during this process. Answer: 8.10 kJ/K Analysis From the steam tables (Tables A-4 through A-6)
