water flows through pipe of diff areas what volume, speed?

at left end diameter is 5 cm. right side diameter is 3 cm. Water flows out of the right at 15 m/s and into the atmosphere.

1. What volume of water flows through pipe in 10 minutes?

2. What is the speed of water in the left section of the pipe?

PLEASE HELP ASAP final COMING

    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
