Absolute humidity at inside temperature in dehumidification Solution

Follow our step by step solution on how to calculate Absolute humidity at inside temperature in dehumidification?

FIRST Step Consider the formula

Yi = Yg - (\frac{(h1 \cdot (Ti - Tl)) - hg \cdot (Tg - Ti)}{k y \cdot hfg})

Next Step Substitute values of Variables

∴

Yi = 16 - (\frac{(10.8W/m²*K \cdot (30 - 20)) - 40W/m²*K \cdot (100 - 30)}{90mol/s*m² \cdot 90J/kg*K})

Next Step Prepare to Evaluate

∴

Yi = 16 - (\frac{(10.8 \cdot (30 - 20)) - 40 \cdot (100 - 30)}{90 \cdot 90})

Next Step Evaluate

∴

Yi = 16.3323456790123

LAST Step Rounding Answer

∴

Yi = 16.3323
