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

Frictional Factor of Laminar flow Formula

Friction factor = 64/Reynolds Number
f = 64/Re

What is a laminar flow?

Laminar flow is a flow regime characterized by high momentum diffusion and low momentum convection. When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity and viscosity of the fluid: laminar flow or turbulent flow.
