Number your responses to correspond with each question e.g. 1a 1b 1c 2a 2b 3a 3b 4a 4b 4c.1. (a) Why do we typically think of health only in terms of health care and personal behaviors? (b) What are the sources of these messages? (c) Who benefits from them? Explain.2. (a) What social and economic conditions support and encourage healthy choices? (b) What social and economic structures affect health that have nothing to do with individual choices?3. When confronted with evidence of health inequities many people from United States respond that the outcomes are unfortunate but not necessarily unjust. (a) Define the term just . (b) Do you agree or disagree that the outcomes are not necessarily unjust? Explain why or why not.4. (a) What policies at the local state or federal level (e.g. education transportation employment etc.) might reduce social and economic inequities? (b) What would a more equitable society look like? (c) Who can make it happen?*Utilizing and citing at least two new academic sources investigate and expand upon all four questions. Your class textbook WILL NOT count as a new academic source; Use APA style; See Rubric.

Reconsider Prob. 1233. Using EES (or other) software investigate the effect of temperature on the fraction of radiation emitted in the visible range. Let the surface temperature vary from 1000 K to 4000 K and plot fraction of radiation emitted in the visible range versus the surface temperature. Problem. 1233 The temperature of the filament of an incandescent light bulb is 3000 K. Treating the filament as a blackbody determine the fraction of the radiant energy emitted by the filament that falls in the visible range. Also determine the wavelength at which the emission of radiation from the filament peaks.

Heat dissipated from an engine in operation can cause hot spots on i

Heat dissipated from an engine in operation can cause hot spots on its surface. If the outer surface of an engine is situated in a place where oil leakage is possible then when the leaked oil comes in contact with hot spots above the oils auto ignition temperature it can ignite spontaneously. Consider an engine outer surface that can be approximated as a blackbody. To prevent fire hazard in the event of oil leak on the engine surface the surface temperature of the engine should be kept below 180C. A radiometer is placed normal to and at a distance of 1 m from the engine surface to monitor the surface temperature. The radiometer receives radiation from a target area of 1 cm2 of the engine surface. If the radiometer detects an irradiation of 0.1 W/m2 would there be any risk of fire hazard?

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.

A long metal sheet that can be approximated as a blackbody is being conveyed through a water bath to be cooled. In order to prevent thermal burn on people handling the sheet it must exit the water bath at a temperature below 45C. A radiometer is placed normal to and at a distance of 0.5 m from the sheet surface to monitor the exit temperature. The radiometer receives radiation from a target area of 1 cm2 of the metal sheet surface. When the radiometer detects that the metal sheet temperature is not below 45C an alarm will go off to warn that the sheet is not safe to touch. Determine the irradiation on the radiometer that the warning alarm should be triggered.

A radiometer is employed to monitor the temperature of manufactured

A radiometer is employed to monitor the temperature of manufactured parts (A1 = 10 cm2) on a conveyor. The radiometer is placed at a distance of 1 m from and normal to the manufactured parts. When a part moves to the position normal to the radiometer the sensor measures the radiation emitted from the part. In order to prevent thermal burn on people handling the manufactured parts at the end of the conveyor the temperature of the parts should be below 45C. An array of spray heads is programmed to discharge mist to cool the parts when the radiometer detects a temperature of 45C or higher on a part. If the manufactured parts can be approximated as black body determine the irradiation on the radiometer that should trigger the spray heads to release cooling mist when the temperature is not below 45C.

A long metal bar (cp = 450 J/kg.K = 7900 kg/m3) is being conveyed

A long metal bar (cp = 450 J/kg.K = 7900 kg/m3) is being conveyed through a water bath to be quenched. The metal bar has a cross section of 30 mm 15 mm and it enters the water bath at 700C. During the quenching process 500 kW of heat is released from the bar in the water bath. In order to prevent thermal burn on people handling the metal bar it must exit the water bath at a temperature below 45C. A radiometer is placed normal to and at a distance of 1 m from the bar to monitor the exit temperature. The radiometer receives radiation from a target area of 1 cm2 of the bar surface. Irradiation signal detected by the radiometer is used to control the speed of the bar being conveyed through the water bath so that the exit temperature is safe for handling. If the radiometer detects an irradiation of 0.015 W/m2 determine the speed of the bar being conveyed through the water bath. Assume that the metal bar can be approximated as a blackbody.

A tank is filled with chemicals undergoing an exothermic reaction. The reaction heats up the tank wall and to prevent thermal burn on individuals the tanks outer surface temperature should be below 45C. The emissivity of the tank surface is 0.85 and irradiation on the tank surface from the surroundings is estimated to be 390 W/m2. Aradiometer is placed normal to and at a distance of 0.5 m from the tank surface to monitor the surface temperature. The radiometer receives radiation from a target area of 1 cm2 of the tank surface. If the irradiation measured by the radiometer is 0.085 W/m2 determine whether or not the tank surface is safe to touch.

Consider an opaque horizontal plate that is well insulated on the edges and the lower surface. The plate is uniformly irradiated from above while air at T = 300 K flows over the surface providing a uniform convection heat transfer coefficient of 40 W/m2K. Under steady state conditions the surface has a radiosity of 4000 W/m2 and the plate temperature is maintained uniformly at 350 K. If the total absorptivity of the plate is 0.40 determine (a) the irradiation on the plate (b) the total reflectivity of the plate (c) the emissive power of the plate and (d) the total emissivity of the plate.
