Theoretical discharge for Venturimeter Solution

Follow our step by step solution on how to calculate Theoretical discharge for Venturimeter?

FIRST Step Consider the formula

Q = \frac{A 1 \cdot A t \cdot (\sqrt{2 \cdot g \cdot h venturi})}{\sqrt{{(A 1)}^{2} - {(A t)}^{2}}}

Next Step Substitute values of Variables

∴

Q = \frac{120cm² \cdot 25cm² \cdot (\sqrt{2 \cdot 9.8m/s² \cdot 24mm})}{\sqrt{{(120cm²)}^{2} - {(25cm²)}^{2}}}

Next Step Convert Units

∴

Q = \frac{0.012m² \cdot 0.0025m² \cdot (\sqrt{2 \cdot 9.8m/s² \cdot 0.024m})}{\sqrt{{(0.012m²)}^{2} - {(0.0025m²)}^{2}}}

Next Step Prepare to Evaluate

∴

Q = \frac{0.012 \cdot 0.0025 \cdot (\sqrt{2 \cdot 9.8 \cdot 0.024})}{\sqrt{{(0.012)}^{2} - {(0.0025)}^{2}}}

Next Step Evaluate

∴

Q = 0.00175310975965599m³/s

LAST Step Rounding Answer

∴

Q = 0.0018m³/s
