Flow rate and velocity form a Conical tank.

I am working on a Hydro project. Just can't get this right.

I have a water tank (cone shaped) with Radius 60 Inches and height 120 Inches. The Tip of the cone has a nozzle with a 3 inch opening. If the Air pressure is ignored. What will be the flow rate of water and pressure. ?

hm.. interesting question, i do not have a solution myself, but here are some stuff that comes to my mind while thinking of this question.

The flow rate is not constant, as flow rate depend on height of the water that is in the conical tank. therefore, as the water level in the tank decreases, the flow rate at the nozzle varies.

seem like we need to apply the continuity equation, Bernoulli's principle and Torricelli theorem.

thats all i can think of, would be nice if someone can come up with a solution for this =D
