Q1: A 3-m3 rigid tank contains steam at 225°C. 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.

1. A rigid tank contains 0.2 kg of a steam-water mixture at 100 kPa. Heat is added until the substance becomes saturated vapor at 1.0 MPa. Determine (a) the initial quality (b) the heat added; and (c) the tank's volume.

Please show your work.  Thank you!

Classify the following states of 1 kg of water substance as wet, dry saturated, superheated steam, subcooled liquid, etc.:  (a) p = 0.1 MPa, T = 150C ,                  (b) p = 0.2 MPa, T  = 200C    (c) p = 0.2 MPa, S = 6.2 kJ/K,                            (d) p = 0.2 MPa, V  = 0.1  m3, (e) H = 2900 kJ, S = 6.2 kJ/K,

A rigid tank (0.010 m³) contains saturated liquid water at 160 deg C. How much heat (kJ) must be added for the pressure to be 800 kPa and a temperature of 200 deg C?

A 2.8 m^3 rigid tank is filled with saturated liquid vapor mixture of water at 300C. If 2% of its volume is liquid and the rest is vapor, the total mass in the tank in kg is?

A real gas exists at 130 C and 1.2 MPa. It is known that the critical temperature and critical pressure of the gas is 374.2 k and 4.059 MPa. It is also know that the ideal gas constant (R) of the gas is 0.12 kPa-m/ S/kg-K. In the question that follows, select the answer that is closest to the true value. Use the compressibility factor (Z) to determine the specific volume in units of m/kg. ,3, Tuesday Dece mber 7 2021 5:52:58 DM CST
