Weep Point Velocity in Distillation Column Design Solution

Follow our step by step solution on how to calculate Weep Point Velocity in Distillation Column Design?

FIRST Step Consider the formula

u h = \frac{K 2 - 0.90 \cdot (25.4 - d h)}{{(ρ V)}^{0.5}}

Next Step Substitute values of Variables

∴

u h = \frac{30 - 0.90 \cdot (25.4 - 0.005m)}{{(1.71kg/m³)}^{0.5}}

Next Step Convert Units

∴

u h = \frac{30 - 0.90 \cdot (25.4 - 5mm)}{{(1.71kg/m³)}^{0.5}}

Next Step Prepare to Evaluate

∴

u h = \frac{30 - 0.90 \cdot (25.4 - 5)}{{(1.71)}^{0.5}}

Next Step Evaluate

∴

u h = 8.9013304741778m/s

LAST Step Rounding Answer

∴

u h = 8.9013m/s
