Please, I need help with the 3 questions. I have tried solving them but the result is not consistent with other things im finding online... How do I even calculate the net on the first question...1)Consider a domestic hot water tank that has a total surface area of A = 2.9 m2. The tank and its contents are maintained at a constant temperature of 58 °C by an electric immersion heater and the temperature of the surroundings outside the tank is 19°C. The emissivity of the tank is ε = 0.76. Calculate the net power radiated by the tank (i.e. the difference between the power radiated and the power absorbed). Give your final answer to an appropriate number of significant figures. 2)The tank is now completely surrounded by an insulating layer of rock mineral wool of thickness l = 0.115 m. The thermal conductivity of rock mineral wool is k = 0.032 W m−1 K−1.You may assume that the surface area of the layer of rock mineral wool is the same as the surface area of the tank. Calculate the power…
