STEAM TABLE AND DRYNESS FRACTION

Steam table

Contoh saturated water and steam💦🌫



Ni simbol simbol yg digunakan dlm steam table kat atas😉
  • P = Pressure of the steam/water
  • T = Saturation point of steam/water (boiling point)
  • vf = Specific volume of saturated water (liquid).
  • vg = Specific volume of saturated steam (gas).
  • hf = Specific enthalpy of saturated water (energy required to heat water from 0°C (32°F) to the boiling point)
  • hfg = Latent heat of evaporation (energy required to transform saturated water into dry saturated steam)
  • hg = Specific enthalpy of saturated steam (total energy required to generate steam from water at 0°C (32°F)

Dryness fraction
Dryness fraction adalah titik x atau percentage atau perkali 

Titik x dryness fraction ni ada dekat garisan saturated mixture yang dlm graf kat bawah ni


Titik x tu dah diberi nilai dia... contohnya titik pengakhiran untuk liqiud tu 
x=0 maksudnya..
0% adalah steam
100% adalah water

X=0.1
10% steam
90% water

X=0.5
50% steam
50%water

X=0.9
90%steam
10% water

X=1 
100% steam
0%water
  
ni formula nak cari dryness fraction



contoh soalan dan jalan kerja dryness fraction

tapi nak buat soalan ni kene rujuk steam table jugak untuk nak dpt kan nilai😉
