v? ²/2 + P? /ρ + gh? = v? ²/2 + P? /ρ + gh?
⇒ v? ²/2 + (P? + ρgh + mg/A)/ρ + g × 0 = v? ²/2 + P? /ρ + g × 0
⇒ v? ²/2 + (ρgh + mg/A)/ρ = v? ²/2 . (1)
Using Continuity equation, we can write
Av? = av? ⇒ v? = (a/A)v?
Putting the value of v? in equation (1), we have
(a²/A²)v? ²/2 + (ρgh + mg/A)/ρ = v? ²/2
