Velocity of Flow in Pipe by Manning Formula given Radius of Pipe Solution

STEP 0: Pre-Calculation Summary

Formula Used

Flow Velocity = sqrt((Head Loss*0.157*(2*Pipe Radius)^(4/3))/(Pipe Length*Manning Coefficient^2))
v_f = sqrt((h_f*0.157*(2*R)^(4/3))/(Lp_'*n^2))
This formula uses 1 Functions, 5 Variables

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

Flow Velocity - (Measured in Meter per Second) - Flow Velocity refers to the speed at which a fluid, such as a liquid or gas, moves through a particular area within a given time.
Head Loss - (Measured in Meter) - Head Loss is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system.
Pipe Radius - (Measured in Meter) - The Pipe Radius is the radius of the pipe through which the fluid is flowing.
Pipe Length - (Measured in Meter) - Pipe Length describes the length of the pipe in which the liquid is flowing.
Manning Coefficient - Manning Coefficient is dimensionless and varies depending on the type of channel or surface through which water flows.

STEP 1: Convert Input(s) to Base Unit

Head Loss: 1.2 Meter --> 1.2 Meter No Conversion Required
Pipe Radius: 200 Millimeter --> 0.2 Meter (Check conversion here)
Pipe Length: 4.9 Meter --> 4.9 Meter No Conversion Required
Manning Coefficient: 0.009 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

v_f = sqrt((h_f*0.157*(2*R)^(4/3))/(Lp_'*n^2)) --> sqrt((1.2*0.157*(2*0.2)^(4/3))/(4.9*0.009^2))

Evaluating ... ...

v_f = 11.8278704931143

STEP 3: Convert Result to Output's Unit

11.8278704931143 Meter per Second --> No Conversion Required

FINAL ANSWER

11.8278704931143 ≈ 11.82787 Meter per Second <-- Flow Velocity
