Lobster got trapped and now is stuck in a restaurant Lobster tank (which is a cube with side L and filled to the brim with water); Frog is coming to the rescue. Unfortunately, the ladder Frog brought is a lightweight plastic one that floats, so Frog resorts to draining the water tank by opening the faucet (with circular cross section d) at the bottom of the tank. Make a thorough drawing of the situation. What is the pressure at the bottom of the tank? With what velocity is the water leaving through the spigot? What is the water's trajectory? How long does it take to empty the tank?
