Inlet Channel Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Inlet Velocity = Maximum Cross Sectional Average Velocity*sin(2*pi*Duration of Inflow/Tidal Period)
c₁ = V_m*sin(2*pi*t/T)
This formula uses 1 Constants, 1 Functions, 4 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Functions Used

sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)

Variables Used

Inlet Velocity - (Measured in Meter per Second) - Inlet Velocity is the velocity of the flow at state 1 or inlet.
Maximum Cross Sectional Average Velocity - (Measured in Meter per Second) - Maximum Cross Sectional Average Velocity during a tidal cycle which is the periodic rise and fall of the waters of the ocean and its inlets.
Duration of Inflow - (Measured in Hour) - Duration of Inflow is the period over which a stream or river carries a consistent flow of water into a system.
Tidal Period - (Measured in Hour) - 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

Maximum Cross Sectional Average Velocity: 4.1 Meter per Second --> 4.1 Meter per Second No Conversion Required
Duration of Inflow: 1.2 Hour --> 1.2 Hour No Conversion Required
Tidal Period: 130 Second --> 0.0361111111111111 Hour (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

c₁ = V_m*sin(2*pi*t/T) --> 4.1*sin(2*pi*1.2/0.0361111111111111)

Evaluating ... ...

c₁ = 4.07010638380204

STEP 3: Convert Result to Output's Unit

4.07010638380204 Meter per Second --> No Conversion Required

FINAL ANSWER

4.07010638380204 ≈ 4.070106 Meter per Second <-- Inlet Velocity

(Calculation completed in 00.021 seconds)

What is Inlet flow patterns?

Seiches are standing waves or oscillations of the free surface of a body of water in a closed or semi-closed basin. These oscillations are of relatively long periods, extending from minutes in harbours and bays to over 10 hr in the Great Lakes. Any external perturbation to the lake or embayment can force an oscillation. In harbours, the forcing can be the result of short waves and wave groups at the harbour entrance. Examples include 30- to 400-sec wave-forced oscillations in the Los Angeles-Long Beach harbour (Seabergh 1985).

What is Inlet flow Pattern & Tidal Prism?

An Inlet has a "gorge" where flows converge before they expand again on the opposite side. Shoal (shallow) areas that extend backward and oceanward from the gorge depend on inlet hydraulics, wave conditions, and general geomorphology. All these interact to determine flow patterns in and around the inlet and locations where flow channels occur.
A 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. The inter-tidal prism volume can be expressed by the relationship: P=H A, where H is the average tidal range and A is the average surface area of the basin.
