The flow of water in a horizontal pipe is stream line flow. Along the pipe, at a point where cross-sectional area is $$10 \text{ cm}^2$$, the velocity of water flow is $$1.00 \text{ ms}^{-1}$$ and the pressure is 2000 Pa. The pressure of water at another point where cross-sectional area is $$5 \text{ cm}^2$$ is

A

2000 Pa

B

1500 Pa

C

3500 Pa

D

500 Pa
