Head Loss in Downcomer of Tray Tower Solution

STEP 0: Pre-Calculation Summary

Formula Used

Downcomer Headloss = 166*((Liquid Mass Flowrate/(Liquid Density*Downcomer Area)))^2
h_dc = 166*((L_w/(ρ_L*A_d)))^2
This formula uses 4 Variables

Variables Used

Downcomer Headloss - (Measured in Meter) - Downcomer Headloss is defined in the loss in the pressure head due to downcomer area or clearance area whichever is smaller.
Liquid Mass Flowrate - (Measured in Kilogram per Second) - Liquid Mass Flowrate is the mass flow rate of the liquid component in the column.
Liquid Density - (Measured in Kilogram per Cubic Meter) - Liquid Density is defined as the ratio of mass of given fluid with respect to the volume that it occupies.
Downcomer Area - (Measured in Square Meter) - Downcomer area refers to the section or passage that allows the liquid phase to flow from the higher tray or stage to the lower tray or stage.

STEP 1: Convert Input(s) to Base Unit

Liquid Mass Flowrate: 12.856 Kilogram per Second --> 12.856 Kilogram per Second No Conversion Required
Liquid Density: 995 Kilogram per Cubic Meter --> 995 Kilogram per Cubic Meter No Conversion Required
Downcomer Area: 0.09872 Square Meter --> 0.09872 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_dc = 166*((L_w/(ρ_L*A_d)))^2 --> 166*((12.856/(995*0.09872)))^2

Evaluating ... ...

h_dc = 2.84356631345434

STEP 3: Convert Result to Output's Unit

2.84356631345434 Meter --> No Conversion Required

FINAL ANSWER

2.84356631345434 ≈ 2.843566 Meter <-- Downcomer Headloss

What is Head Loss in Downcomer in Distillation?

Head loss in the downcomer of a distillation column is the reduction in pressure experienced by the liquid as it flows from a higher tray (stage) to a lower one through the downcomer. This head loss is a crucial factor in the design and operation of distillation columns as it affects the distribution of liquid and vapor flow within the column. The head loss in the downcomer can be caused by various factors, including frictional resistance, changes in velocity, and changes in elevation.
