A household iron has a stainless steel sole plate that weights 3 lb and has a surface
Question:
A household iron has a stainless steel sole plate that weights 3 lb and has a surface area of 0.5 ft2. The iron is rated at 500 W. If the surroundings are at a temperature of 80°F, and the convective heat-transfer coefficient between the sole plate and surroundings is 3 Btu/h ft2 °F, how long will it take for the iron to reach 240°F after it is plugged in?
