Consider a bowl that has a quadratic cylindrically symmetric profile with height-dependent z² diameter given by d(z) = . The bottom of the bowl at z = 0 has a hole with a 0.05 mm² area. 10 cm If the bowl is initially filled to a depth of 10 cm with water, how long will it take for half of the water to drain out the hole? You may consider the system to be quasistatic and inviscid.
