Hot water with a mass flow rate of 3 kg/s and a temperature of 90 degrees Celsius enters a 2-inch copper pipe with a length of 3 m. The pipe is exposed to cold air at the constant temperature of 1C and wind velocity is 5 m/s. Find the outlet temperature of the water and the rate of heat loss from the pipe.
