Pressure in flushing hole Solution

Follow our step by step solution on how to calculate Pressure in flushing hole?

FIRST Step Consider the formula

P 1 = P atm + (P r - P atm) \cdot (\frac{\ln (\frac{R 0}{R 1})}{\ln (\frac{R 0}{r})})

Next Step Substitute values of Variables

∴

P 1 = 10.1325N/cm² + (4.38N/cm² - 10.1325N/cm²) \cdot (\frac{\ln (\frac{2.07cm}{2cm})}{\ln (\frac{2.07cm}{2.6cm})})

Next Step Convert Units

∴

P 1 = 101325Pa + (43800Pa - 101325Pa) \cdot (\frac{\ln (\frac{0.0207m}{0.02m})}{\ln (\frac{0.0207m}{0.026m})})

Next Step Prepare to Evaluate

∴

P 1 = 101325 + (43800 - 101325) \cdot (\frac{\ln (\frac{0.0207}{0.02})}{\ln (\frac{0.0207}{0.026})})

Next Step Evaluate

∴

P 1 = 110005.985424841Pa

Next Step Convert to Output's Unit

∴

P 1 = 11.0005985424841N/cm²

LAST Step Rounding Answer

∴

P 1 = 11.0006N/cm²
