Venturi Head given Theoretical Discharge through Pipe Solution

Follow our step by step solution on how to calculate Venturi Head given Theoretical Discharge through Pipe?

FIRST Step Consider the formula

h venturi = {((\frac{Q th}{A i \cdot A f}) \cdot (\sqrt{\frac{{(A i)}^{2} - {(A f)}^{2}}{2 \cdot [g]}}))}^{2}

Next Step Substitute values of Variables

∴

h venturi = {((\frac{1.277m³/s}{7.1m² \cdot 1.8m²}) \cdot (\sqrt{\frac{{(7.1m²)}^{2} - {(1.8m²)}^{2}}{2 \cdot [g]}}))}^{2}

Next Step Substitute values of Constants

∴

h venturi = {((\frac{1.277m³/s}{7.1m² \cdot 1.8m²}) \cdot (\sqrt{\frac{{(7.1m²)}^{2} - {(1.8m²)}^{2}}{2 \cdot 9.8066m/s²}}))}^{2}

Next Step Prepare to Evaluate

∴

h venturi = {((\frac{1.277}{7.1 \cdot 1.8}) \cdot (\sqrt{\frac{{(7.1)}^{2} - {(1.8)}^{2}}{2 \cdot 9.8066}}))}^{2}

Next Step Evaluate

∴

h venturi = 0.0240123846645442m

Next Step Convert to Output's Unit

∴

h venturi = 24.0123846645442mm

LAST Step Rounding Answer

∴

h venturi = 24.0124mm
