Liquid layer temperature in dehumidification Solution

Follow our step by step solution on how to calculate Liquid layer temperature in dehumidification?

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

Tl = 353K - (\frac{(40W/m²*K \cdot (100 - 353K)) + 90J/kg*K \cdot 90mol/s*m² \cdot (16 - 50.7)}{10.8W/m²*K})

Next Step Prepare to Evaluate

∴

Tl = 353 - (\frac{(40 \cdot (100 - 353)) + 90 \cdot 90 \cdot (16 - 50.7)}{10.8})

Next Step Evaluate

∴

Tl = 27315.037037037

LAST Step Rounding Answer

∴

Tl = 27315.037
