Barlow's Formula for Pipe Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pressure = (2*Applied stress*Wall Thickness)/(Outside Diameter)
P = (2*σ*t)/(D_o)
This formula uses 4 Variables

Variables Used

Pressure - (Measured in Pascal) - Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
Applied stress - (Measured in Pascal) - Applied stress is denoted by the symbol σ.
Wall Thickness - (Measured in Meter) - Wall Thickness is simply the width of the wall that we are taking under consideration.
Outside Diameter - (Measured in Meter) - Outside Diameter is the diameter of the outside surface.

STEP 1: Convert Input(s) to Base Unit

Applied stress: 93.3 Pascal --> 93.3 Pascal No Conversion Required
Wall Thickness: 7.83 Meter --> 7.83 Meter No Conversion Required
Outside Diameter: 0.05 Meter --> 0.05 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = (2*σ*t)/(D_o) --> (2*93.3*7.83)/(0.05)

Evaluating ... ...

P = 29221.56

STEP 3: Convert Result to Output's Unit

29221.56 Pascal --> No Conversion Required

FINAL ANSWER

29221.56 Pascal <-- Pressure

Diameter of Pipe given Head Loss due to Laminar Flow

Go Diameter of Pipe = ((128*Viscous Force head loss*Rate of flow*Change in Drawdown)/(Specific weight of liquid*pi*Head loss))^(1/4)

Viscous Force using Head loss Due to Laminar Flow

Go Viscous Force head loss = Head loss*Specific Weight*pi*(Pipe Diameter^4)/(128*Rate of flow*Change in Drawdown)

Length of Pipe given Head loss

Go Change in Drawdown = Head loss*Specific Weight*pi*(Pipe Diameter^4)/(128*Rate of flow*Viscous Force head loss)

Head Loss due to Laminar Flow

Go Head loss = (128*Viscous Force head loss*Rate of flow*Change in Drawdown)/(pi*Specific Weight*Pipe Diameter^4)

Heat Loss due to Pipe

Go Heat Loss due to Pipe = (Force*Length*Fluid Velocity^2)/(2*Diameter*Acceleration Due To Gravity)

Depth of Centroid given Total Hydrostatic Force

Go Depth of Centroid = Hydrostatic Force/(Specific Weight 1*Surface area)

Head Loss using Efficiency of Hydraulic Transmission

Go Head loss = Total Head at Entrance-Efficiency*Total Head at Entrance

Viscous Stress

Go Viscous Stress = Dynamic Viscosity*Velocity Gradient/Fluid Thickness

Barlow's Formula for Pipe

Go Pressure = (2*Applied stress*Wall Thickness)/(Outside Diameter)

Coefficient of Discharge at Venacontracta of Orifice

Go Coefficient of Discharge = Coefficient of Contraction*Coefficient of Velocity

Viscous Force Per Unit Area

Go Viscous Force = Force/Area

Frictional Factor of Laminar flow

Go Friction factor = 64/Reynolds Number
