Reconsider Prob. 1258. Using the EES (or other) software evaluate the effect of the position of the approaching object on the irradiation ratio G2 x / G2 0 where G2 x and G2 0 are the irradiation on the radiometer when the object is at position x and at x = 0 respectively. By varying x from 0 to 3 m with 0.2 m increments plot irradiation ratio G2 x/G2 0 as a function of the approaching object position x for the placement of the radiometer at H = 0.5 1.0 and 1.5 m. Problem. 1258 A radiometer can be used to determine the position of an approaching hot object by measuring the amount of irradiation it detects. Consider a radiometer placed at a distance H = 0.5 m from the x-axis is used to measure the position of an approaching small blackbody object. If the radiometer is measuring 80% of the irradiation corresponding to the position of the object directly under the radiometer (x = 0) determine the position of the object L.
