Internal Water Pressure using Buttress Resistance Solution

Follow our step by step solution on how to calculate Internal Water Pressure using Buttress Resistance?

FIRST Step Consider the formula

p i = ((\frac{P BR}{2 \cdot A cs \cdot \sin (\frac{θ b}{2})}) - (\frac{γ water \cdot ({V fw}^{2})}{[g]}))

Next Step Substitute values of Variables

∴

p i = ((\frac{1500kN}{2 \cdot 13m² \cdot \sin (\frac{36°}{2})}) - (\frac{9.81kN/m³ \cdot ({5.67m/s}^{2})}{[g]}))

Next Step Substitute values of Constants

∴

p i = ((\frac{1500kN}{2 \cdot 13m² \cdot \sin (\frac{36°}{2})}) - (\frac{9.81kN/m³ \cdot ({5.67m/s}^{2})}{9.8066m/s²}))

Next Step Convert Units

∴

p i = ((\frac{1.5E+6N}{2 \cdot 13m² \cdot \sin (\frac{0.6283rad}{2})}) - (\frac{9810N/m³ \cdot ({5.67m/s}^{2})}{9.8066m/s²}))

Next Step Prepare to Evaluate

∴

p i = ((\frac{1.5E+6}{2 \cdot 13 \cdot \sin (\frac{0.6283}{2})}) - (\frac{9810 \cdot ({5.67}^{2})}{9.8066}))

Next Step Evaluate

∴

p i = 154536.347248398Pa

Next Step Convert to Output's Unit

∴

p i = 154.536347248398kN/m²

LAST Step Rounding Answer

∴

p i = 154.5363kN/m²
