Been stuck on this question for ages!

I'm not sure what formula to use here in order to solve this problem?

Any help would be appreciated! Thanks

You need to use the specific heat formula,

where is the (heat) energy into the system (out if negative), is the mass of the material, is its specific heat capacity and is the temperature. Since you're looking for the rate of heat loss, you can introduce the rate of flow of mass to the right hand side of the equation to equalise.

where is the rate of flow of volume and is the density of water, as stated in the question.

Then substituting values in:

Therefore, the rate of heat loss is 1772.4 W. Technically speaking, we only know this answer correct to 1 significant figure (so 2000 W), due to the given rate of flow of volume, but I'll assume that isn't important.

not trying to be a bummer or anything like that but you shouldve given hits or tips to the person asking for help and not given the answer to them straight away.

That's fair; I did consider leaving it at just specific heat capacity, but sometimes I feel a worked solution is more useful, especially when the question is a little more unconventional. Granted, I could've at least left the answer itself out.
