An inverted conical tank of 2 m radius and 4 m height is initially full of water, has an outlet at bottom. The outlet is opened at some instant. The rate of flow through the outlet at any time t is 6h3/2, where h is height of water level above the outlet at time t. Then the time it takes to empty the tank is

- \(\frac{\pi}{9} \text { units }\)
- \(\frac{2 \pi}{8} \text { units }\)
- none of these
Answer
(D) none of these
