Time needed to empty a pressurized oil tank

  1. Dec 18, 2015 #1
    hello everybody! i'm discussing since a couples of days with a friend of mine about an pneumo-idraulic energy storage.
    The basic concept is to pump oil when there is excess power production fro renewable energy in a direct contact fluid/to gas hydraulic accumulator, in function to pressurize the gas, and get back the energy when is needed in the night time.. the question we can't answer is: how much time it takes, lets say, 1000 liter of hydraulic oil contained ina 1meter cube round tank , to come out form a 10 mm diameter hole, form a initial pressure of 100 bars knowing that the last 100 liters will stay inside the tank? and how much power it can generate? thanks a lot!!
