Stack Design Pressure Draft for Furnace Solution

Follow our step by step solution on how to calculate Stack Design Pressure Draft for Furnace?

FIRST Step Consider the formula

P Draft = 0.0342 \cdot (L s) \cdot P Atm \cdot (\frac{1}{T Ambient} - \frac{1}{T Flue Gas})

Next Step Substitute values of Variables

∴

P Draft = 0.0342 \cdot (6500mm) \cdot 100000Pa \cdot (\frac{1}{298.15K} - \frac{1}{350K})

Next Step Convert Units

∴

P Draft = 0.0342 \cdot (6.5m) \cdot 100000Pa \cdot (\frac{1}{298.15K} - \frac{1}{350K})

Next Step Prepare to Evaluate

∴

P Draft = 0.0342 \cdot (6.5) \cdot 100000 \cdot (\frac{1}{298.15} - \frac{1}{350})

Next Step Evaluate

∴

P Draft = 11.0454996286625m

Next Step Convert to Output's Unit

∴

P Draft = 11045.4996286625mm

LAST Step Rounding Answer

∴

P Draft = 11045.4996mm
