T V Diagram For Steam Water

The saturated water curve liquid line is obtained by plotting p and v f values form the steam tables on p v co ordinates and t s f values on t s coordinates.

T v diagram for steam water. This video explains how to draw t v diagrams and what they represent. I 221 2 bar ii 374 15 c. The saturation temperature for water at 1 014 bar is 100oc. 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.

Process 1 2 isothermal expansion the water is isothermally converted into dry saturated steam at a constant temperature t1 and pressure p1. Notice that the t v diagram is based exclusively on intensive properties hence mass is not indicated on the diagram. Enjoy the videos and music you love upload original content and share it all with friends family and the world on youtube. On the t v and p v diagrams provided below not to scale sketch and label the following processes for steam water.

Jsc arrows to indicate the direction of the process and label the initial and final states. For water the 3d p v t diagram is seen here. This is the saturated liquid state corresponding to 1 014 bar. Figure 3 2 2 sketch of t v diagram for water4 as the water is heated at constant pressure the temperature increases with a slight increase in specific volume until the system reaches point f.

The diagram below can be used to determine enthalpy versus entropy of water and steam. 3d phase diagram of water fluids and selected ices an orthographic projection of the 3d p v t graph showing pressure and temperature as the vertical and horizontal axes collapses the 3d plot into the standard 2d pressure temperature diagram. Dry state of steam is expressed in point 2. 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.

Principle processes efficiency with p v and t s diagram 1. Notice that the t v diagram is based exclusively on intensive properties hence mass is not indicated on the diagram. Similarly saturated vapour steam line or curves are obtained from steam tables.
