Power Lost Solution

Follow our step by step solution on how to calculate Power Lost?

FIRST Step Consider the formula

P loss = ρ Fluid \cdot q flow \cdot 0.5 \cdot {(V - V f)}^{2}

Next Step Substitute values of Variables

∴

P loss = 0.5kg/m³ \cdot 24m³/s \cdot 0.5 \cdot {(6m/s - 5m/s)}^{2}

Next Step Prepare to Evaluate

∴

P loss = 0.5 \cdot 24 \cdot 0.5 \cdot {(6 - 5)}^{2}

LAST Step Evaluate

∴

P loss = 6W
