Which of the following exists in a PV diagram for water when water is heated from 10 0c to 200 0c at 1 atm?
Determine (a) the quality of the fluid and the mass of the vapor at state (2), and (b) the pressure of the fluid at state (3). Step 1: Always draw a complete diagram of the states and processes of the problem and include all the relevant information on the diagram.
Which of the following exists in a PV diagram for water?
Which of the following exists in a p-V diagram for water? Explanation: The p-V diagram for water has all these three lines. The triple point is a line on the p-V diagram, where all the three phases, solid, liquid and gas exist.
How is saturation curve formed on TV diagram?
All the saturated vapor states are connected to create the saturated vapor line. 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. The pressure is changed by removing the weight.
What is a saturated liquid line?
A saturation state is the point where a phase change begins or ends. For example, the saturated liquid line represents the point where any further addition of energy will cause a small portion of the liquid to convert to vapor.
What is the name of the point at which the saturated liquid and saturated vapor states are identical?
the critical point
Then, at a certain pressure, the mixture region will be represented only by one point. This point is called the critical point. It is defined as the point at which the saturated liquid and saturated vapor states are identical.
What is the state at which saturated liquid line with respect to vaporization and saturated vapor line on PV diagram of pure substance meet called?
critical point
The point at which the saturated liquid line with respect to vaporization and saturated vapor on a P-V diagram of a pure substance is called the critical point.
What is the saturated solid state *?
ANSWER: a state at which solid can change into liquid at constant pressure and temperature.
What is the saturated solid state Mcq?
a state at which solid can change into liquid at constant pressure but changing temperature.
How PV diagram is different from PT diagram?
It has been found that on a ‘p-T’ diagram the triple point is represented by a point and on a ‘p-v’ diagram it is a line, and on a ‘u-v’ diagram it is a triangle. In the case of ordinary water, the triple point is at a pressure of 4.58 mm Hg and a temperature of 0.01°C.
How do you calculate saturated liquid?
IF v = vf THEN the fluid is saturated liquid and the values of pressure, internal energy uf, enthalpy hf, and entropy sf are read directly from the row corresponding to the known temperature T. IF v > vf AND v < vg THEN the fluid is a saturated mixture of liquid and vapor phases.
What is the state at which saturated liquid line with respect to vaporization and saturated Vapour line on PV diagram of pure substance MIT called?
How do you calculate the PV of saturated water?
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. used to look up the properties for various substances at many temperatures and pressures LOOK at Tables A-4 and A-5 for saturated water (in SI units, Appendix 2 has English units)
What is the vapor pressure and saturation pressure of water?
The vapour pressure of water is the pressure at which water vapour is in thermodynamic equilibrium with its condensed state. At higher pressures water would condense. At this equilibrium condition the vapor pressure is the saturation pressure. The calculator below can be used to calculate the water saturation pressure at given temperatures.
What is the T-V value of saturated mixture?
No saturated mixture exists – the substance changes directly from the liquid to vapor states. T CR = 374.14 o C (or 647.3 o K) v CR = 0.003155 m 3 /kg (or .0568 m 3 /kmol) MORE T-v DIAGRAMS (Figure 2-15): P-v DIAGRAMS (Figure 2-16): Note: Constant Temperature lines go downward.
A line connected by all the saturated liquid states is called saturated liquid line. All the saturated vapor states are connected to create the saturated vapor line. When pressure becomes as high as P cr (critical pressure), the saturated liquid state and the saturated vapor state become a single point in T-v diagram.
