Froude Number given Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Froude Number = Mean Velocity for Froude Number/sqrt([g]*Diameter of Section)
Fr = V_FN/sqrt([g]*d_section)
This formula uses 1 Constants, 1 Functions, 3 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Froude Number - Froude Number is a measurement of bulk flow characteristics such as waves, sand bedforms, flow/depth interactions at a cross section or between boulders.
Mean Velocity for Froude Number - (Measured in Meter per Second) - Mean Velocity for Froude Number is defined as the average velocity of a fluid at a point and over an arbitrary time T.
Diameter of Section - (Measured in Meter) - The Diameter of Section refers to the length of the segment that passes through the center of the circle and touches two points on the edge of the circle.

STEP 1: Convert Input(s) to Base Unit

Mean Velocity for Froude Number: 70 Meter per Second --> 70 Meter per Second No Conversion Required
Diameter of Section: 5 Meter --> 5 Meter No Conversion Required

STEP 2: Evaluate Formula
