Assume the mostly infrared radiation from a heat lamp acts like a continuous wave with wavelength 1.50 µm . If the lamp’s 200-W output is focused on a person’s shoulder, over a circular area 25.0 cm in diameter, then how long will it take to increase the temperature of the 4.00-kg shoulder by 2.00°C, assuming no other heat transfer and given that its specific heat is 3.47 × 103 J/kg. °C ?
Consider a 3-m * 3-m * 3-m cubical furnace whose top and side surfaces closely approximate black surfaces at a temperature of 1200 K. The base surface has an emissivity of « = 0.4, and is maintained at 800 K. Determine the net rate of radiation heat transfer to the base surface from the top and side surfaces.
Solar radiation reaches Earth at a rate of about 1,400 W/m2. If all this energy were absorbed, what would be the average force exerted by radiation pressure on a square meter oriented at right angles to the sunlight?
Sunlight strikes the surface of a lake at an angle of incidence of 59.9°. At what angle with respect to the normal would a fish see the Sun?
Two parallel disks of diameter D = 3 ft separatedby L = 2 ft are located directly on top of each other. Thedisks are separated by a radiation shield whose emissivity is0.15. Both disks are black and are maintained at temperaturesof 1200 R and 700 R, respectively. The environment that thedisks are in can be considered to be a blackbody at 540 R.Determine the net rate of radiation heat transfer through theshield under steady conditions.
Two coaxial parallel disks of equal diameter 1 m are originally placed at a distance of 1 m apart. If both disks behave as black surfaces, determine the new distance between the disks such that there is a 75% reduction in radiation heat transfer rate from the original distance of 1 m.
To maximize the radiation pressure on the sails of a spacecraft using solar sailing, should the sheets be (a) very black to absorb as much sunlight as possible or (b) very shiny to reflect as much sunlight as possible?
The hot-water needs of a household are to be met by heating water at 55°F to 180°F by a parabolic solar collector at a rate of 4 lbm/s. Water flows through a 1.25-in-diameter thin aluminum tube whose outer surface is black-anodized in order to maximize its solar absorption ability. The centerline of the tube coincides with the focal line of the collector, and a glass sleeve is placed outside the tube to minimize the heat losses. If solar energy is transferred to water at a net rate of 400 Btu/h per ft length of the tube, determine the required length of the parabolic collector to meet the hot-water requirements of this house.
A slab of glass 0.2mthick absorbs 50% of the light passing through it. How thick must a slab of identical glass be in order to absorb 90% of the light passing through it? How thick must it be to absorb 99% of the light? How thick to absorb 99.9% of the light?
The fraction of nonreflected radiation that is transmitted through a 5-mm thickness of a transparent material is 0.95. If the thickness is increased to 12 mm, what fraction of light is transmitted?
A radiometer has two square vanes (2.0 cm by 2.0 cm), attached to a light horizontal cross arm, and pivoted about a vertical axis through the center. The center of each vane is 12.0 cm from the axis. One vane is silvered and it reflects all radiant energy incident upon it. The other vane is blackened and it absorbs all incident radiant energy. Radiant energy, having an intensity of 600 W/m2 , is incident normally upon the vanes. What is the radiation pressure on the blackened vane?
