A pipe discharges wine into a 15m diameter tankAnother pipe

A pipe discharges wine into a 1.5m diameter tank.Another pipe ( 15 cm diameter), located near the base of the tank,is used to discharge wine out of the tank. Calculate the volumetricflow rate into the tank if the wine level remains constant at 2.5m.

volumetricflow rate will be

2.5 * 1.5 / 15/100 = 25 m^3 / sec
