Question 7

A non-viscous, incompressible liquid of density 1000 kg/m³ flows smoothly through a horizontal tube with a constriction in it, as in the diagram. The diameter in section A is twice the diameter in the constricted section B; the speed of flow in A is v₁ = 50 cm/s, and the pressure P₁ in A is 2.00*10⁴ Pa. The pressure P₂ in section B is:

• A.    4.00*10⁴ Pa
• B.    1.00*10⁴ Pa
• C.    5.00*10⁴ Pa
• D.    1.81*10⁴ Pa
• E.    1.96*10⁴ Pa
• F.    2.00*10⁴ Pa
