Laminar Flow Fountain

10 m into the air nozzle has a 2 cm diameter at ground level. The water pump is 2.5 m below the ground. The hose to the nozzle has a diameter of 4 cm. Suppose that the inviscid laminar flow. Find the pump pressure required.

The diameter of the pipe should not matter if it is non-viscous flow.
What is the pressure of 12.5 meters of water?

Bah.
