Seal resistance Solution

Follow our step by step solution on how to calculate Seal resistance?

FIRST Step Consider the formula

F 0 = F friction - (μ \cdot A \cdot p)

Next Step Substitute values of Variables

∴

F 0 = 294N - (0.3 \cdot 82.5mm² \cdot 4.24MPa)

Next Step Convert Units

∴

F 0 = 294N - (0.3 \cdot 8.3E-5m² \cdot 4.2E+6Pa)

Next Step Prepare to Evaluate

∴

F 0 = 294 - (0.3 \cdot 8.3E-5 \cdot 4.2E+6)

LAST Step Evaluate

∴

F 0 = 189.06N

How to Evaluate Seal resistance?

Seal resistance evaluator uses Seal Resistance = Friction Force in Elastic Packing-(Coefficient of Friction in Elastic Packing*Area of Seal Contacting Sliding Member*Fluid Pressure in Elastic Packing) to evaluate the Seal Resistance, The Seal resistance formula is defined as the opposition force experienced by the object in motion. Seal Resistance is denoted by F₀ symbol.

How to evaluate Seal resistance using this online evaluator? To use this online evaluator for Seal resistance, enter Friction Force in Elastic Packing (F_friction), Coefficient of Friction in Elastic Packing (μ), Area of Seal Contacting Sliding Member (A) & Fluid Pressure in Elastic Packing (p) and hit the calculate button.

FAQs on Seal resistance

What is the formula to find Seal resistance?

The formula of Seal resistance is expressed as Seal Resistance = Friction Force in Elastic Packing-(Coefficient of Friction in Elastic Packing*Area of Seal Contacting Sliding Member*Fluid Pressure in Elastic Packing). Here is an example- 188.8125 = 294-(0.3*8.25E-05*4240000).

How to calculate Seal resistance?

With Friction Force in Elastic Packing (F_friction), Coefficient of Friction in Elastic Packing (μ), Area of Seal Contacting Sliding Member (A) & Fluid Pressure in Elastic Packing (p) we can find Seal resistance using the formula - Seal Resistance = Friction Force in Elastic Packing-(Coefficient of Friction in Elastic Packing*Area of Seal Contacting Sliding Member*Fluid Pressure in Elastic Packing).

Can the Seal resistance be negative?

No, the Seal resistance, measured in Force cannot be negative.

Which unit is used to measure Seal resistance?

Seal resistance is usually measured using the Newton[N] for Force. Exanewton[N], Meganewton[N], Kilonewton[N] are the few other units in which Seal resistance can be measured.
