A boy has a tank with a rectangular bottom base 40 cm by 50 cm and a height of 100 cm. The tank is initially empty and is equipped with an orifice 3 mm square (Cv=0.96 and Cc=0.62) located at the bottom of the tank. The boy first closed the orifice and start pouring water into the tank at a constant rate of 0.05 li/s. After 30 minutes, without the boy noticing it, the orifice was accidentally opened and it took another 30 minutes when the boy noticed that the orifice was already opened. What is the depth of water in the tank at that moment?
