Internal diameter = 2cm
Internal radius = 1cm
Volume of water in the tank in 1 second = pi * 1^2 * 600 cm^3
Volume of water in the tank in 30 minutes = pi * 1^2 * 600 * 30 * 60 cm^3
Base area of tank=pi*r^2 = pi*60^2
Volume of water in tank = pi*60^2*h cm^3
Therefore pi*60^2*h cm^3 = pi * 1^2 * 600 * 30 * 60 cm^3
or 3600*h = 600 * 30 * 60
or h = 300 cm or 3 meters

Base area of tank=pi*r^2 = pi*60^2
Volume of water in tank = pi*60^2*h cm^3
Therefore pi*60^2*h cm^3 = pi * 1^2 * 600 * 30 * 60 cm^3
or 3600*h = 600 * 30 * 60
or h = 300 cm or 3 meters
