Question

Use the picture as a guide. P is the pressure in the pipe, and v_i is the speed of a non-viscous incompressible fluid at locations i = 1,2,3,4,5.(For each statement select G-Greater than, L-Less than, or E-Equal to).

A) P₃ is .... P₄
B) P₁ is .... P₄
C) v₁ is .... v₂
D) v₁ is .... 2v₃
E) P₁ is .... P₂
F) v₄ is .... v₅
G) P₄ is .... P₅

Answer 1

A) P3 is ..Greater .. P4 (diameter of the tube is same but height is less)
B) P1 is .Less... P4 (height is same but diameter is large so pressure is high but speed is less)
C) v1 is .Equal... v2 Equation of continuity   
D) v1 is . Greater... 2v3     Equation of continuity   
E) P1 is ..Greater.. P2 Potential energy reduces pressure
F) v4 is .Equal ... v5 Equation of continuity
G) P4 is .Greater... P5     Potential energy reduces pressure
