Flow Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Flow Velocity = Resultant Velocity*sin(Angle)
V_f = V*sin(θ)
This formula uses 1 Functions, 3 Variables

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

Flow Velocity - (Measured in Meter per Second) - Flow Velocity is the velocity of fluids at a certain time and position and is referred to as the flow speed.
Resultant Velocity - (Measured in Meter per Second) - Resultant Velocity is the sum of its vector velocities. The sum of the vector forces on an object equals the scalar product of its mass and acceleration vector.
Angle - (Measured in Radian) - Angle made with the direction of the boat aligned in the direction of the resultant velocity or made with the direction of the flow.

STEP 1: Convert Input(s) to Base Unit

Resultant Velocity: 10 Meter per Second --> 10 Meter per Second No Conversion Required
Angle: 50 Degree --> 0.872664625997001 Radian (Check conversion here)

Resultant Velocity given Flow Velocity

Go Resultant Velocity = Flow Velocity/sin(Angle)

Moving Boat Velocity

Go Boat Velocity = Resultant Velocity*cos(Angle)

Flow Velocity

Go Flow Velocity = Resultant Velocity*sin(Angle)

Flow Velocity Formula

Flow Velocity = Resultant Velocity*sin(Angle)
V_f = V*sin(θ)

What is Moving-Boat Technique for measurement of Velocity?

The Moving- Boat Technique measures the velocity over the width of a segment by suspending the current meter at a constant depth during the traverse of the boat across the stream. The measured velocity and the additional information of the depth sounding gives the required data for determining the discharge.
