Surface Pressure using Wilhelmy-Plate Method Solution

STEP 0: Pre-Calculation Summary

Formula Used

Surface Pressure of Thin Film = -(Change in Force/(2*(Thickness of Plate+Weight of Plate)))
Π = -(ΔF/(2*(t+W_plate)))
This formula uses 4 Variables

Variables Used

Surface Pressure of Thin Film - (Measured in Pascal) - The Surface Pressure of Thin Film is the difference in interfacial tension between a clean interface and an interface in the presence of an emulsifier.
Change in Force - (Measured in Newton) - The Change in Force is the difference between the initial and final force exerted on an object.
Thickness of Plate - (Measured in Meter) - Thickness of Plate is defined as the thickness of plate (usually the lowest dimension of the plate) under consideration.
Weight of Plate - (Measured in Kilogram) - The Weight of Plate is defined as the force of attraction exerted on the plate by gravity.

STEP 1: Convert Input(s) to Base Unit

Change in Force: -0.015 Newton --> -0.015 Newton No Conversion Required
Thickness of Plate: 5000 Millimeter --> 5 Meter (Check conversion here)
Weight of Plate: 16.9 Gram --> 0.0169 Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Π = -(ΔF/(2*(t+W_plate))) --> -((-0.015)/(2*(5+0.0169)))

Evaluating ... ...

Π = 0.00149494707887341

STEP 3: Convert Result to Output's Unit

0.00149494707887341 Pascal --> No Conversion Required

FINAL ANSWER

0.00149494707887341 ≈ 0.001495 Pascal <-- Surface Pressure of Thin Film
