My name is Ann [436]

Answer:

d = 2*0.87 = 1.75 cm

Explanation:

by using flow rate equation to determine the  speed in larger pipe

\phi =\pi r^2 v

v = \frac{\phi}{\pi r^2}

  = \frac{2900 cm^3/s}{3.14(1.25cm)^2}

= 591.10 cm/s

 = 5.91 m/s

by Bernoulli's EQUATION

p1 +\frac{1}{2} \rho v1^2 = p2 +\frac{1}{2} \rho v2^2

139000+ \frac{1}{2}*1000*5.91^2 = 101000 +\frac{1}{2}*1000* v2^2

solving for v2

v2 = 10.53 m/s

diameter can be determine by using flow rate equation

q = v \pi r^2

r^2 = \frac{q}{\pi v}

     = \frac{2900}{3.14*1053}

r = 0.87 cm

d = 2*0.87 = 1.75 cm
