STEP 1: Convert Input(s) to Base Unit

Liquid Enthalpy at Point 2: 150 Kilojoule per Kilogram --> 150000 Joule per Kilogram (Check conversion here)
Dryness Fraction at Point 2: 0.2 --> No Conversion Required
Latent Heat of Fusion: 1000 Kilojoule per Kilogram --> 1000000 Joule per Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h₂ = h_f2+(x₂*h_fg) --> 150000+(0.2*1000000)

Evaluating ... ...

h₂ = 350000

STEP 3: Convert Result to Output's Unit

350000 Joule per Kilogram -->350 Kilojoule per Kilogram (Check conversion here)

FINAL ANSWER

350 Kilojoule per Kilogram <-- Enthalpy of The Vapour Refrigerant at T2
