A storage tank contains water contaminated with a small quantity of a soluble hazardos waste material. The tank is 3 m in diameter and 6 m high . At the current time the liquid height is within 1 m of the top of the tank.
1. If a 3-cm(internal diameter) feed pipe at the bottom of the tank breaks off, how much
liquid (in m^3)is spilled if an emergency response procedure require 30 min to stop the flow?
2. What is the final liquid level (in m)?
3. What is the maximum spill rate of liquid (in kg/s)?
Assume that the tank is vented.
