The flow of blood in a large artery of an anesthetised dog is diverted through a Venturi meter. The wider part of the meter has a cross-sectional area equal to that of the artery. A = 8 ${\mathrm{mm}}^{2}$. The narrower part has an area a = 4 ${\mathrm{mm}}^{2}$. The pressure drop in the artery is 24 Pa. What is the speed of the blood in the artery?

(Density of blood = )

1.   145 m/s

2.   0.145 m/s

3.   123 m/s

4.   0.123 m/s
