Problem

A jet of oil leaves a large pipe of internal diameter

5\,\text{cm}

with a speed of

2.0\,\text{m s}^{-1}

and enters a nozzle of diameter

2\,\text{cm}

fitted to the pipe. Neglecting any change in density, the speed of the oil in the nozzle is (a)

25.0\,\text{m s}^{-1}

(b)

5.0\,\text{m s}^{-1}

(c)

12.5\,\text{m s}^{-1}

(d)

8.0\,\text{m s}^{-1}
