1. Volumetric Flow Rate = Area x velocity

So go with the right:

VFR = A x v = pi(1.5)^2 x 15m/s(1000cm/m)

= 10,597.5 cm^3/s

VFR x time = Volume

(10,597.5cm^3/s) (10min)(60seconds/min)

= 6,358,500cm^3

or

= 6.36 m^3

2. VFR1 = VFR2

Area1 x Velocity1 = Area2 x Velocity2

A1v1/A2 = v2

7.065cm^2(15m/s) / (19.625cm^2) = v2

v2 = 5.4m/s
