Pressure in Bubble Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pressure = (8*Surface Tension)/Diameter of Bubble
p = (8*σ)/d_b
This formula uses 3 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.
Surface Tension - (Measured in Newton per Meter) - Surface Tension is a word that is linked to the liquid surface. It is a physical property of liquids, in which the molecules are drawn onto every side.
Diameter of Bubble - (Measured in Meter) - Diameter of Bubble is defined as their conclusion is that, with the increase of gas flow rate , the bubble frequency decreases and the bubble diameter increases.

STEP 1: Convert Input(s) to Base Unit

Surface Tension: 55 Newton per Meter --> 55 Newton per Meter No Conversion Required
Diameter of Bubble: 61000 Millimeter --> 61 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

p = (8*σ)/d_b --> (8*55)/61

Evaluating ... ...

p = 7.21311475409836

STEP 3: Convert Result to Output's Unit

7.21311475409836 Pascal --> No Conversion Required

FINAL ANSWER

7.21311475409836 ≈ 7.213115 Pascal <-- Pressure

Force Acting in x Direction in Momentum Equation

Go Force in X-Direction = Density of Liquid*Discharge*(Velocity at Section 1-1-Velocity at Section 2-2*cos(Theta))+Pressure at Section 1*Cross-Sectional Area at Point 1-(Pressure at Section 2*Cross-Sectional Area at Point 2*cos(Theta))

Force Acting in y-Direction in Momentum Equation

Go Force in Y-Direction = Density of Liquid*Discharge*(-Velocity at Section 2-2*sin(Theta)-Pressure at Section 2*Cross-Sectional Area at Point 2*sin(Theta))

Experimental Determination of Metacentric height

Go Metacentric Height = (Movable Weight on Ship*Transverse Displacement)/((Movable Weight on Ship+Ship Weight)*tan(Angle of Tilt))

Radius of Gyration given Time Period of Rolling

Go Radius of Gyration = sqrt(Acceleration Due to Gravity*Metacentric Height*(Time Period of Rolling/2*pi)^2)

Fluid Dynamic or Shear Viscosity Formula

Go Dynamic Viscosity = (Applied Force*Distance between Two Masses)/(Area of Solid Plates*Peripheral Speed)

Moment of Inertia of Waterline Area using Metacentric Height

Go Moment of Inertia of Waterline Area = (Metacentric Height+Distance Between Point B and G)*Volume of Liquid Displaced by Body

Volume of Liquid Displaced given Metacentric Height

Go Volume of Liquid Displaced by Body = Moment of Inertia of Waterline Area/(Metacentric Height+Distance Between Point B and G)

Distance between Buoyancy Point and Center of Gravity given Metacenter Height

Go Distance Between Point B and G = Moment of Inertia of Waterline Area/Volume of Liquid Displaced by Body-Metacentric Height

Metacentric Height given Moment of Inertia

Go Metacentric Height = Moment of Inertia of Waterline Area/Volume of Liquid Displaced by Body-Distance Between Point B and G

Center of Gravity

Go Centre of Gravity = Moment of Inertia/(Volume of Object*(Centre of Buoyancy+Metacenter))

Center of Buoyancy

Go Centre of Buoyancy = Moment of Inertia/(Volume of Object*Centre of Gravity)-Metacenter

Metacenter

Go Metacenter = Moment of Inertia/(Volume of Object*Centre of Gravity)-Centre of Buoyancy

Theoretical Velocity for Pitot Tube

Go Theoretical Velocity = sqrt(2*Acceleration Due to Gravity*Dynamic Pressure Head)

Metacentric Height

Go Metacentric Height = Distance between Point B and M-Distance Between Point B and G

Volume of Submerged Object given Buoyancy Force

Go Volume of Object = Buoyancy Force/Specific Weight of Liquid

Buoyancy Force

Surface Tension given Surface Energy and Area

Go Surface Tension = (Surface Energy)/(Surface Area)

Pressure in Bubble

Go Pressure = (8*Surface Tension)/Diameter of Bubble

Surface Energy given Surface Tension

Go Surface Energy = Surface Tension*Surface Area

Surface Area given Surface Tension

Go Surface Area = Surface Energy/Surface Tension

Pressure in Bubble Formula

Pressure = (8*Surface Tension)/Diameter of Bubble
p = (8*σ)/d_b

What is the pressure inside a bubble?

2γ/R is the Laplace pressure. The ΔP is 2 times the Laplace pressure since there is a complete sphere instead of a semi sphere on a layer of water. Based on the diameter, the pressure inside an air bubble in pure water, where γ = 72 mN/m at 25°C (298 K), can vary greatly.

Why pressure inside bubble is more than outside?

There are two free surfaces of soap bubble. Due to surface tension, the molecules on the surface film experience the net force in the inward direction normal to the surface. Therefore, there is more pressure inside than outside.
