Vessel Blockage Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Vessel Blockage Ratio = Vessel’s Midsection Wetted Cross-Sectional Area/(Water Depth at Breaking*Channel Width corresponding to Mean Water Depth)
S = A_m/(d_b*W)
This formula uses 4 Variables

Variables Used

Vessel Blockage Ratio - Vessel Blockage Ratio is a measure used in maritime engineering and hydrodynamics to describe the extent to which a vessel occupies a waterway, such as a canal, river, or lock.
Vessel’s Midsection Wetted Cross-Sectional Area - (Measured in Square Meter) - Vessel’s Midsection Wetted Cross-Sectional Area is the area of the vertical plane that cuts through the widest part (beam) of the submerged portion of a vessel's hull.
Water Depth at Breaking - (Measured in Meter) - Water Depth at Breaking is the depth of water where ocean surface waves start to break as they approach the shore which depends on the wave climate and is therefore highly variable.
Channel Width corresponding to Mean Water Depth - (Measured in Meter) - Channel Width corresponding to Mean Water Depth is the width of a natural or engineered channel where the average depth of the water is taken into consideration.

STEP 1: Convert Input(s) to Base Unit

Vessel’s Midsection Wetted Cross-Sectional Area: 31 Square Meter --> 31 Square Meter No Conversion Required
Water Depth at Breaking: 55 Meter --> 55 Meter No Conversion Required
Channel Width corresponding to Mean Water Depth: 52 Meter --> 52 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S = A_m/(d_b*W) --> 31/(55*52)

Evaluating ... ...

S = 0.0108391608391608

STEP 3: Convert Result to Output's Unit

0.0108391608391608 --> No Conversion Required

FINAL ANSWER

0.0108391608391608 ≈ 0.010839 <-- Vessel Blockage Ratio

FAQ

What is Vessel Blockage Ratio?

The Vessel Blockage Ratio formula refers to the dimensionless parameter used in naval architecture and marine engineering to quantify the extent to which a vessel obstructs the flow of water in a confined channel or waterway. It is an important factor in understanding the hydrodynamic effects and navigational challenges posed by a vessel in restricted waters, such as canals, rivers, and harbor entrances and is represented as S = A_m/(d_b*W) or Vessel Blockage Ratio = Vessel’s Midsection Wetted Cross-Sectional Area/(Water Depth at Breaking*Channel Width corresponding to Mean Water Depth). Vessel’s Midsection Wetted Cross-Sectional Area is the area of the vertical plane that cuts through the widest part (beam) of the submerged portion of a vessel's hull, Water Depth at Breaking is the depth of water where ocean surface waves start to break as they approach the shore which depends on the wave climate and is therefore highly variable & Channel Width corresponding to Mean Water Depth is the width of a natural or engineered channel where the average depth of the water is taken into consideration.
