10-kW heater using Nichrome wire is to be designed. The surface of the Nichrome is to belimited to a maximum temperature of 1650 K. Other design criteria for the heater are:*minimum convective heat-transfer coefficient: 850 W/m2٠K*temperature of the surrounding medium (air): 370 KThe resistivity of Nichrome is 110 µΩ-cm and the power to the heater is available at 12 volts.What diameter wire is required if the heater is to be in one piece 0.6 m long?
