Question: The heating element of a water heater in an apartment building has a maximum power output of 28 kW.
Four residents of the building take showers at the same time, and each receives heated water at a volume flow rate of 20x10-5 m3/s.
If the water going into the heater has a temperature of 19°C,
Q: What is the maximum possible temperature of the hot water that each showering resident receives?
This one is complex and I don't know how to find the temperature of the hot water?
