Your manager wants you to design a new superinsulated hot-waterheater for the residential market. A coil of Nichrome wire is to beused as the heating element. Calculate the length of wire required.(The water heater is cylindrical in shape, and is completely filledwith water. Let the diameter of the water heater be 50 cm and itsheight 0.8 m. The coil of Nichrome wire is located inside the waterheater, in contact with the water. Assume that the diameter of theNichrome wire is 2.0 mm and that the water, initially at 20°C, isto be heated to 77°C in 1.0 h. Let the voltage used by the waterheater be 120 V.)
