You just copied the same answer from Chegg but that one is incorrect... so far these are the results i got but i also think they're not correct. 4(a) The power radiated by the tank can be expressed in the following formula: P = εσA(Tin4 – Tout4) Where, ε = 0.76 σ = 5.67 x 10^-8 W/m2K^4 A = 2.8 m^2 T(Tin^4 – Tout^4) = (58 + 273.15 = 331.15 K)^4 – (19 + 273.15 = 292.15 K)^4 = 4740486867.42 K So Pnet= 0.76 * 5.67 × 10^-8 * 2.9 * 4740486867.42 Pnet = 592.4 W or 0.59 kW 4(b) The power lost through the insulating layer can be calculated using the following formula: Ploss = kA Ttan⁡k−Ts / l where Ploss is the power lost through the insulating layer, k is the thermal conductivity of the rock mineral wool, A is the surface area of the tank, Ttan⁡k is the temperature of the tank, Ts is the temperature of the surroundings, and l is the thickness of the insulating layer. k = 0.032 A = 2.9 m^2 Ttan⁡k = 58 °C Ts = 19°C l= 0.115 m Ploss = 0.032 * 2.9 * 58−19/115 Ploss = 31.47 W…

The emissivity of the human skin is 97.0 percent. Use 35.0 °C for the skin temperature and approximate the human body by a rectangular block with a height of 1.77 m, a width of 33.0 cm and a length of 29.5 cm. 1. Calculate the power emitted by the human body. 2. What is the wavelength of the peak in the spectral distribution for this temperature? 3. Fortunately our environment radiates too. The human body absorbs this radiation with an absorbance of 97.0 percent, so we don't lose our internal energy so quickly. How much power do we absorb when we are in a room where the temperature is 26.0 °C? 4. How much energy does our body lose in one second? Please answer all four parts

A 0.3-cm-thick, 12-cm-high, and 18-cm-long circuit board houses 80 closely spaced logic chips on one side, each dissipating 0.06 W. The board is impregnated with copper fillings and has an effective thermal conductivity of 16 W/m·K. All the heat generated in the chips is conducted across the circuit board and is dissipated from the back side of the board to the ambient air. Determine the temperature difference between the two sides of the circuit board.
