Problem

A horizontal pipeline carries water (density

1.0\times10^{3}\,\text{kg\,m}^{-3}

). At point A the pipe diameter is 6.0 cm, the flow speed is 2.0 m s

^{-1}

, and the gauge pressure is 120 kPa. Downstream at point B the diameter is 3.0 cm. Assuming ideal flow, what is the gauge pressure at point B? a)

60\text{ kPa}

150\text{ kPa}

90\text{ kPa}

114\text{ kPa}
