Question

A 1.0-cm-diameter pipe widens to 2.0 cm, then narrows to 5.0 mm. Liquid flows through the first segment at a speed of 7.0 m/s. 

Part A 

What is the speed in the second segment? 

Part B 

What is the speed in the third segment? Express your answer with the appropriate units. 

Part C 

What is the volume flow rate through the pipe? Express your answer with the appropriate units. 

Answer 1

Given that m 3, = 0.5x108 72 = 1.0 x10 a 1.0 Xioam 33 = 2.5x1 103 V, = 7.0 mis es Continuity Equation Vei= Ve an V, T7,2 TT V, x8,2 V2 = 13 = 7.0x0.5x1082 (1.0x 10-22 A] = 1.75 m/s B] Br = 0,8? 8,82 = 8 ♡ = 7.0% (0.5X10-222 (2.5x10-372 = 28 mis

in all 6] volume flow rake is the same three segments, Segments, and is Equal al to Q-A, Q ухт T8,2 Q = 7x TI X(0,5x10-832 Q = 50495x10.4 miles
