Theoretical Velocity at Section 1 in Orifice Meter Solution

Follow our step by step solution on how to calculate Theoretical Velocity at Section 1 in Orifice Meter?

FIRST Step Consider the formula

V 1 = \sqrt{({V p2}^{2}) - (2 \cdot [g] \cdot h venturi)}

Next Step Substitute values of Variables

∴

V 1 = \sqrt{({34m/s}^{2}) - (2 \cdot [g] \cdot 24mm)}

Next Step Substitute values of Constants

∴

V 1 = \sqrt{({34m/s}^{2}) - (2 \cdot 9.8066m/s² \cdot 24mm)}

Next Step Convert Units

∴

V 1 = \sqrt{({34m/s}^{2}) - (2 \cdot 9.8066m/s² \cdot 0.024m)}

Next Step Prepare to Evaluate

∴

V 1 = \sqrt{(34^{2}) - (2 \cdot 9.8066 \cdot 0.024)}

Next Step Evaluate

∴

V 1 = 33.9930769539917m/s

LAST Step Rounding Answer

∴

V 1 = 33.9931m/s
