Atmospheric pressure Solution

Follow our step by step solution on how to calculate Atmospheric pressure?

FIRST Step Consider the formula

P atm = P 1 - (\frac{Q \cdot 6 \cdot μ v \cdot \ln (\frac{R 0}{R 1})}{π \cdot h^{3}})

Next Step Substitute values of Variables

∴

P atm = 11N/cm² - (\frac{0.18m³/s \cdot 6 \cdot 10.2P \cdot \ln (\frac{5cm}{4cm})}{π \cdot {2cm}^{3}})

Next Step Substitute values of Constants

∴

P atm = 11N/cm² - (\frac{0.18m³/s \cdot 6 \cdot 10.2P \cdot \ln (\frac{5cm}{4cm})}{3.1416 \cdot {2cm}^{3}})

Next Step Convert Units

∴

P atm = 110000Pa - (\frac{0.18m³/s \cdot 6 \cdot 1.02Pa*s \cdot \ln (\frac{0.05m}{0.04m})}{3.1416 \cdot {0.02m}^{3}})

Next Step Prepare to Evaluate

∴

P atm = 110000 - (\frac{0.18 \cdot 6 \cdot 1.02 \cdot \ln (\frac{0.05}{0.04})}{3.1416 \cdot {0.02}^{3}})

Next Step Evaluate

∴

P atm = 100219.334457363Pa

Next Step Convert to Output's Unit

∴

P atm = 10.0219334457363N/cm²

LAST Step Rounding Answer

∴

P atm = 10.0219N/cm²

FAQs on Atmospheric pressure

What is the formula to find Atmospheric pressure?

The formula of Atmospheric pressure is expressed as Atmospheric Pressure = Pressure in Flushing Hole-((Flow Rate of the Electrolyte*6*Dynamic Viscosity*ln(Radius of the Electrodes/Radius of Flushing Hole))/(pi*Gap Spacing^3)). Here is an example- -0.00053 = 110000-((0.18*6*1.02*ln(0.05/0.04))/(pi*0.02^3)).

How to calculate Atmospheric pressure?

With Pressure in Flushing Hole (P₁), Flow Rate of the Electrolyte (Q), Dynamic Viscosity (μ_v), Radius of the Electrodes (R₀), Radius of Flushing Hole (R₁) & Gap Spacing (h) we can find Atmospheric pressure using the formula - Atmospheric Pressure = Pressure in Flushing Hole-((Flow Rate of the Electrolyte*6*Dynamic Viscosity*ln(Radius of the Electrodes/Radius of Flushing Hole))/(pi*Gap Spacing^3)). This formula also uses Archimedes' constant and Natural Logarithm (ln) function(s).

Can the Atmospheric pressure be negative?

Yes, the Atmospheric pressure, measured in Pressure can be negative.

Which unit is used to measure Atmospheric pressure?

Atmospheric pressure is usually measured using the Newton per Square Centimeter[N/cm²] for Pressure. Pascal[N/cm²], Kilopascal[N/cm²], Bar[N/cm²] are the few other units in which Atmospheric pressure can be measured.
