Please help and write it out clearly, and step by step. Happy to give a like for help!

15 points 2. A "thermal outfall" from a coastal coal fired power plant discharges 5Mm3/ day of seawater at 35C into coastal waters. (The water being discharged had been warmed when it was used to condense warm steam after it had moved through turbine electrical generators.) If the ambient temperature of the seawater is 19C, what dilution factor is required to keep the seawater temperature rise to be less than 4C ? Note that a dilution factor of 1 means no dilution. Take the heat capacity of seawater to be 3850kJ/kgC
