Dimensionless Estuary number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Estuary Number = (Volume of Tidal Prism*Froude Number^2)/(Fresh Water River Flow*Tidal Period)
E = (P*Fr^2)/(Q_r*T)
This formula uses 5 Variables

Variables Used

Estuary Number - Estuary Number is used in the study of estuarine circulation, which refers to the residual flow pattern in an estuary induced by the density difference between seawater and river water.
Volume of Tidal Prism - (Measured in Cubic Meter) - Volume of Tidal Prism is the volume of water in an estuary or inlet between mean high tide and mean low tide, or the volume of water leaving an estuary at ebb tide.
Froude Number - Froude Number is the measurement of bulk flow characteristics such as waves, sand bedforms, flow or depth interactions at a cross-section or between boulders.
Fresh Water River Flow - (Measured in Cubic Meter per Second) - Fresh Water River Flow is the degree of mixing in an estuary and can be approximately related to the ratio between the volume of the tidal prism and the river flow.
Tidal Period - (Measured in Second) - Tidal Period is the time taken for a specific site on Earth to rotate from an exact point under moon to same point under moon, also known as “tidal day” and it’s slightly longer than a solar day.

STEP 1: Convert Input(s) to Base Unit

Volume of Tidal Prism: 40 Cubic Meter --> 40 Cubic Meter No Conversion Required
Froude Number: 10 --> No Conversion Required
Fresh Water River Flow: 5 Cubic Meter per Second --> 5 Cubic Meter per Second No Conversion Required
Tidal Period: 130 Second --> 130 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E = (P*Fr^2)/(Q_r*T) --> (40*10^2)/(5*130)

Evaluating ... ...

E = 6.15384615384615

STEP 3: Convert Result to Output's Unit

6.15384615384615 --> No Conversion Required

FINAL ANSWER

6.15384615384615 ≈ 6.153846 <-- Estuary Number

What is an Estuary?

An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone.

How to Calculate Dimensionless Estuary number?

Dimensionless Estuary number calculator uses Estuary Number = (Volume of Tidal Prism*Froude Number^2)/(Fresh Water River Flow*Tidal Period) to calculate the Estuary Number, The Dimensionless Estuary number formula is defined as the parameter used in the study of estuarine circulation, which refers to the residual flow pattern in an estuary induced by the density difference between seawater and river water. Estuary Number is denoted by E symbol.

How to calculate Dimensionless Estuary number using this online calculator?
