Water is flowing through a vertical tube with varying cross section as shown. The rate of flow is 52.5 ml/s. Given that speed of flow $$v_1 = 0.35$$ m/s and area of cross section $$A_2 = 0.5\ \text{cm}^2$$. Which of the following are true?

A

$$A_1 = 1.0\ \text{cm}^2$$ and $$v_2 = 0.70$$ m/s

B

$$A_1 = 1.5\ \text{cm}^2$$ and $$v_2 = 1.05$$ m/s

C

$$h = 5$$ cm

D

$$h = 10$$ cm
