How much time would it take to change the temperature of a room by 10°C by radiation?
Known values:
Stefan-Boltzmann constant σ = 5.67*10^-8
Emissivity ε = 0.9
A = 2 m^2
T1 = 290 K
T2 = 260 K
The equation we should be using is the heat transfer by radiation equation. I don't know how to calculate time from that.

Determine the time it would take to change the temperature by 10°C. The knowns for conductive heat transfer are given below. First, calculate the rate of conductive heat transfer. Then, determine the time it would take to change the temperature by 10°C. k = 0.8 A = 10 m^2 T1 = 290 K T2 = 260 K d = 0.2 m

Radiation of Energy The rate of heat transfer by emitted radiation is determined by the Stefan-Boltzmann law of radiation: = aeAT4 where o 5.67x10-8 J/s - m2 K is the Stefan-Boltzmann constant, A is the surface area of the object, and T is its absolute temperature in kelvin. The symbol e stands for the emissivity of the object, which is a measure of how well it radiates An ideal jet-black (or black body) radiator has e 1,whereas a perfect reflector has...

In this problem you will consider the balance of thermal energy radiated and absorbed by a person in a room. The rate of heat transfer from radiation is: ΔQΔt=eσA(T42−T41)=eσAT42−eσAT41. This equation has two terms which represent the rate of absorption from the room (a gain) and the rate of radiation into the room (a loss). In this problem, we will consider these two terms separately. Assume that the area of a human body may be considered to be that of...
An aluminum alloy (2024) plate, heated to a uniform temperature of 227°C, is allowed to cool while vertically suspended in a room where the ambient air and surroundings are at 27°C. The plate is 0.3 m square with a thickness of 15 mm. a) calculate the rate of heat transfer from the plate to the surrounding air. b) Develop an expression for the time rate of change of the plate temperature, assuming the temperature to be uni form at any...
Radiation heat transfer: Two perfectly black surfaces (each with emissivity ε = 1.0) are constructed such that all the radiant energy leaving a surface at 800 °C (1073 K) reaches the other surface. The temperature of the other surface, with area A = 2 m2, is maintained at 250 °C (523 K). Using the formula Q = ε σ A (THot4 – TCold4) calculate the heat transfer (in kW) of the surface maintained at 800 °C. The Stefan-Boltzmann constant, σ...

An object with a surface area of 0.05 m2 and at 500 K is placed in a large room with wall temperature of 300 K. Estimate the maximum net radiation heat transfer from the surface. State whether this is the total heat transfer rate from the surface of the object and explain. Is the information sufficient for you to evaluate the total heat transfer rate? Take Stefan- Boltzmann’s constant as 5.67 × 10-8 W/m2.K4.
