boleh tahan gak la.....
camni rupanya ooo....first2 saturated liquid pastu compress liquid......then critical point saat nak bertukar jadi gas.....(mix)......then saturated vapor.....yang seterusnya superheated diluar tu....
The properties listed in the tables include
- Saturation pressure (Psat) for a given temperature or saturation temperature (Tsat) for a given pressure
- Specific volume of saturated liquid (vf) and saturated vapor (vg)
- Specific internal energy of saturated liquid (uf), saturated vapor (ug), and vaporization (ufg = ug - uf) jgn silap fg=g-f
- Specific enthalpy of saturated liquid (hf), saturated vapor (hg), and vaporization (hfg = hg - hf) or latent heat of vaporization.
- Specific entropy of saturated liquid (sf), saturated vapor (sg), and vaporization (sfg = sg - sf)
The above process can be repeated for u and h.
uav = uf + ufg x
hav = hf + hfg x jgn silap < rumus perlu dihafal
The format of the subcooled liquid water tables is similar to the format of the superheated vapor tables. In the absence of compressed liquid data, a common practice is to use the saturated liquid data based on the given temperature to estimate the properties of compressed liquid. For h, the error can be reduced using the following approximation
Subcooled liquid (compress liquid) can be characterized by
- P > Psat at a given T
- T < Tsat at a given P <hafal superheated berlawanan compress
- v < vf at a given P or T
- u < uf at a given P or T
- h < hf at a given P or T
