How to find the volumetric flow rate?

[Connor Anderson]

With a given 2kW pump
That pumps a liquid with a density of 820kg/m³ from one tank to another that's 30m higher.
With a calculated change in pressure to be 241.3kpa.
Find the volumetric flow rate.
I feel like there are not enough given variables for this problem. What do you think?

What additional information do you think you need? What formula would try to use?

Welcome to PF:
Just thinking about the height for now...
How much work to lift a mass m of water up a height h?
