Pressure Head Drop Solution

STEP 0: Pre-Calculation Summary

Formula Used

Head Loss due to Friction = (12*Dynamic Viscosity*Length of Pipe*Mean Velocity)/(Specific Weight of Liquid)
h_location = (12*μ*L_p*V_mean)/(γ_f)
This formula uses 5 Variables

Variables Used

Head Loss due to Friction - (Measured in Meter) - The Head Loss due to Friction occurs due to the effect of the fluid's viscosity near the surface of the pipe or duct.
Dynamic Viscosity - (Measured in Pascal Second) - The Dynamic Viscosity refers to the internal resistance of a fluid to flow when a force is applied.
Length of Pipe - (Measured in Meter) - The Length of Pipe refers to total length from one end to another in which the liquid is flowing.
Mean Velocity - (Measured in Meter per Second) - Mean velocity is defined as the average velocity of a fluid at a point and over an arbitrary time T.
Specific Weight of Liquid - (Measured in Kilonewton per Cubic Meter) - The Specific Weight of Liquid refers to the weight per unit volume of that substance.

STEP 1: Convert Input(s) to Base Unit

Dynamic Viscosity: 10.2 Poise --> 1.02 Pascal Second (Check conversion here)
Length of Pipe: 0.1 Meter --> 0.1 Meter No Conversion Required
Mean Velocity: 32.4 Meter per Second --> 32.4 Meter per Second No Conversion Required
Specific Weight of Liquid: 9.81 Kilonewton per Cubic Meter --> 9.81 Kilonewton per Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_location = (12*μ*L_p*V_mean)/(γ_f) --> (12*1.02*0.1*32.4)/(9.81)

Evaluating ... ...

h_location = 4.04256880733945

STEP 3: Convert Result to Output's Unit

4.04256880733945 Meter --> No Conversion Required

FINAL ANSWER

4.04256880733945 ≈ 4.042569 Meter <-- Head Loss due to Friction

Velocity Distribution Profile

LaTeX Go Velocity of Liquid = -(1/(2*Dynamic Viscosity))*Pressure Gradient*(Width*Horizontal Distance-(Horizontal Distance^2))

Distance between Plates using Velocity Distribution Profile

LaTeX Go Width = (((-Velocity of Liquid*2*Dynamic Viscosity)/Pressure Gradient)+(Horizontal Distance^2))/Horizontal Distance

Distance between Plates given Maximum Velocity between Plates

LaTeX Go Width = sqrt((8*Dynamic Viscosity*Maximum Velocity)/(Pressure Gradient))

Maximum Velocity between Plates

LaTeX Go Maximum Velocity = ((Width^2)*Pressure Gradient)/(8*Dynamic Viscosity)

Pressure Head Drop Formula

LaTeX Go

Head Loss due to Friction = (12*Dynamic Viscosity*Length of Pipe*Mean Velocity)/(Specific Weight of Liquid)
h_location = (12*μ*L_p*V_mean)/(γ_f)

What is Pressure Head Loss?

The head loss (or the pressure loss) represents the reduction in the total head or pressure (sum of elevation head, velocity head and pressure head) of the fluid as it flows through a hydraulic system. Although the head loss represents a loss of energy, it does not represent a loss of total energy of the fluid.

How to Calculate Pressure Head Drop?

Pressure Head Drop calculator uses Head Loss due to Friction = (12*Dynamic Viscosity*Length of Pipe*Mean Velocity)/(Specific Weight of Liquid) to calculate the Head Loss due to Friction, The Pressure Head Drop is defined as the loss of energy due to friction acting on the boundary of pipe and non viscous flow. Head Loss due to Friction is denoted by h_location symbol.

How to calculate Pressure Head Drop using this online calculator? To use this online calculator for Pressure Head Drop, enter Dynamic Viscosity (μ), Length of Pipe (L_p), Mean Velocity (V_mean) & Specific Weight of Liquid (γ_f) and hit the calculate button. Here is how the Pressure Head Drop calculation can be explained with given input values -> 4.042569 = (12*1.02*0.1*32.4)/(9810).

FAQ

What is Pressure Head Drop?

The Pressure Head Drop is defined as the loss of energy due to friction acting on the boundary of pipe and non viscous flow and is represented as h_location = (12*μ*L_p*V_mean)/(γ_f) or Head Loss due to Friction = (12*Dynamic Viscosity*Length of Pipe*Mean Velocity)/(Specific Weight of Liquid). The Dynamic Viscosity refers to the internal resistance of a fluid to flow when a force is applied, The Length of Pipe refers to total length from one end to another in which the liquid is flowing, Mean velocity is defined as the average velocity of a fluid at a point and over an arbitrary time T & The Specific Weight of Liquid refers to the weight per unit volume of that substance.
