Datum Height at Section 1 from Bernoulli Equation Solution

Follow our step by step solution on how to calculate Datum Height at Section 1 from Bernoulli Equation?

FIRST Step Consider the formula

Z 1 = \frac{P 2}{γ f} + 0.5 \cdot \frac{{V p2}^{2}}{[g]} + Z 2 - \frac{P 1}{γ f} - 0.5 \cdot \frac{{V 1}^{2}}{[g]}

Next Step Substitute values of Variables

∴

Z 1 = \frac{10N/mm²}{9.81kN/m³} + 0.5 \cdot \frac{{34m/s}^{2}}{[g]} + 12.1m - \frac{8.9N/mm²}{9.81kN/m³} - 0.5 \cdot \frac{{58.03m/s}^{2}}{[g]}

Next Step Substitute values of Constants

∴

Z 1 = \frac{10N/mm²}{9.81kN/m³} + 0.5 \cdot \frac{{34m/s}^{2}}{9.8066m/s²} + 12.1m - \frac{8.9N/mm²}{9.81kN/m³} - 0.5 \cdot \frac{{58.03m/s}^{2}}{9.8066m/s²}

Next Step Convert Units

∴

Z 1 = \frac{1E+7Pa}{9810N/m³} + 0.5 \cdot \frac{{34m/s}^{2}}{9.8066m/s²} + 12.1m - \frac{8.9E+6Pa}{9810N/m³} - 0.5 \cdot \frac{{58.03m/s}^{2}}{9.8066m/s²}

Next Step Prepare to Evaluate

∴

Z 1 = \frac{1E+7}{9810} + 0.5 \cdot \frac{34^{2}}{9.8066} + 12.1 - \frac{8.9E+6}{9810} - 0.5 \cdot \frac{{58.03}^{2}}{9.8066}

Next Step Evaluate

∴

Z 1 = 11.4763326819051m

LAST Step Rounding Answer

∴

Z 1 = 11.4763m
