Empirical constant for AJM Solution

Follow our step by step solution on how to calculate Empirical constant for AJM?

FIRST Step Consider the formula

A 0 = \frac{Z w}{N \cdot {d mean}^{3} \cdot V^{\frac{3}{2}} \cdot {(\frac{ρ}{12 \cdot h b})}^{\frac{3}{4}}}

Next Step Substitute values of Variables

∴

A 0 = \frac{0.16m³/s}{5 \cdot {4mm}^{3} \cdot {1.4E+6m/s}^{\frac{3}{2}} \cdot {(\frac{997kg/m³}{12 \cdot 200kgf/mm²})}^{\frac{3}{4}}}

Next Step Convert Units

∴

A 0 = \frac{0.16m³/s}{5 \cdot {0.004m}^{3} \cdot {1.4E+6m/s}^{\frac{3}{2}} \cdot {(\frac{997kg/m³}{12 \cdot 2E+9Pa})}^{\frac{3}{4}}}

Next Step Prepare to Evaluate

∴

A 0 = \frac{0.16}{5 \cdot {0.004}^{3} \cdot {1.4E+6}^{\frac{3}{2}} \cdot {(\frac{997}{12 \cdot 2E+9})}^{\frac{3}{4}}}

Next Step Evaluate

∴

A 0 = 99.9999999999998

LAST Step Rounding Answer

∴

A 0 = 100
