What is the momentum equation for a quasi – one dimensional flow?

• A. p1A1 + ρ1u\(_1^2\)A1 + \(\int_{A_1}^{A_2}\)pdA = p2A2 + ρ2u\(_2^2\)A2
• B. p1A1u1+ ρ1u\(_1^2\)A1 + \(\int_{A_1}^{A_2}\)pdA = p2A2u2+ ρ2u\(_2^2\)A2
• C. p1A1 + ρ1u\(_1^2\)A1 = p2A2 + ρ2u\(_2^2\)A2
• D. p1A1u1+ ρ1u\(_1^2\)A1 = p2A2u2+ ρ2u\(_2^2\)A2
