A metal pipe with internal diameter of 1 cm is 2 m long and is electrically heated to increase water temperature from 20°C to 40°C before a shower faucet. For a typical shower water mass flow rate of 0.06 kg/s (about 1 gpm), what is the required heat flux that needs to be imposed on the pipe to heat the water? The specific heat of water is 4200 J/kg°C.
