Flow Velocity given Length to Depth Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Flow Velocity = Settling Velocity*Length to depth
V_f = v_s*LH
This formula uses 3 Variables

Variables Used

Flow Velocity - (Measured in Meter per Second) - Flow Velocity is the velocity of the flow of any fluid.
Settling Velocity - (Measured in Meter per Second) - Settling velocity is defined as the terminal velocity of a particle in still fluid.
Length to depth - Length to depth is the ratio of length of the tank to depth of the sedimentation tank.

STEP 1: Convert Input(s) to Base Unit

Settling Velocity: 1.5 Meter per Second --> 1.5 Meter per Second No Conversion Required
Length to depth: 0.9 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_f = v_s*LH --> 1.5*0.9

Evaluating ... ...

V_f = 1.35

STEP 3: Convert Result to Output's Unit

1.35 Meter per Second --> No Conversion Required

FINAL ANSWER

1.35 Meter per Second <-- Flow Velocity

(Calculation completed in 00.004 seconds)
