What is a saturated liquid?

What is a saturated liquid?

Saturated liquid: A liquid that is about to vaporize. At 1 atm and 20°C, water exists in the liquid phase (compressed liquid). At 1 atm pressure and 100°C, water exists as a liquid that is ready to vaporize (saturated liquid).

What is critical point in TV diagram?

When pressure becomes as high as Pcr (critical pressure), the saturated liquid state and the saturated vapor state become a single point in T-v diagram. This point is called the critical point. For water, Pcr equals 22.09 MPa, Tcr (critical temperature) equals 374.14 oC.

What is the critical temperature of water?

In water, the critical point occurs at 647.096 K (373.946 °C; 705.103 °F) and 22.064 megapascals (3,200.1 psi; 217.75 atm). In the vicinity of the critical point, the physical properties of the liquid and the vapor change dramatically, with both phases becoming ever more similar.

How are h and PV formed in thermodynamics?

H is formed by combining the internal energy, U, and work done in the form, PV. PV = (N/m 2 ) (m 3) = N-m = Joules on a per unit mass basis: h = u + Pv (specific enthalpy) H is a function of BOTH temperature and pressure.

Why is mass not indicated on a T-V diagram?

Notice that the T-v diagram is based exclusively on intensive properties, hence mass is not indicated on the diagram. Thus we indicate on the diagram that in order to determine the quality at state (2) we need to first evaluate the specific volume v 2, which can then be compared to the saturation values v f and v g at the pressure of 100 kPa.

How is U and H related in thermodynamics?

U is a function ONLY of the temperature of the substance H is formed by combining the internal energy, U, and work done in the form, PV. PV = (N/m 2 ) (m 3) = N-m = Joules on a per unit mass basis: h = u + Pv (specific enthalpy) H is a function of BOTH temperature and pressure.
