The product of the area of cross section and the speed remains the same at all points of a tube of flow. This is called the equation of continuity and expresses the law of conservation of mass in fluid dynamics. A1v1=A2v2 Bernoulli equation relates the speed of a fluid at a point, the pressure at the point and the height of that point above a reference level. It is given as- P+ρgh+12ρv2=constant It is just the application of work-energy theorem in the case of fluid flow.(a) From the equation of continuity- ⇒A1v1=A2v2⇒(10 cm2)(2.50 m/s)=(3 cm2)v2⇒(10×10-4 m2)(2.50 m/s)=(3×10-4 m2)v2⇒v2=8.33 m/s (b) Apply Bernoulli's equation- ⇒P1+ρgh+12ρv12=P2+ρgh+12ρv22⇒P1+12ρv12=P2+12ρv22⇒P2=P1+12ρ[v12-v22]⇒P2=(1.20×105) + 12(1.65×103 kg/m3)[(2.50)2-(8.33)2]⇒P2=67910.40 PaConclusion: (a) 8.33 m/s(b) 67910.40 Pa
