Our atmosphere provides us with some degree of shielding from cosmic radiation. Suppose shielding efficiency is approximately proportional to the shield material’s density. What depth of water will provide the same shielding as the Earth’s atmosphere? (Hint: the pressure at the surface of the Earth is 1 atm.)
It is often argued that the head is the most important part of the body to cover when out in cold weather. Estimate the total energy loss by radiation if a person’s head is uncovered for 19.4 min on a very cold, −15.0°C day, assuming he is bald, his skin temperature is 35.0°C, and that skin has an emissivity (in the infrared) of 97.0%. Assume that the man’s head is spherical, with a radius of 10.0 cm. The Stefan–Boltzmann constant is 5.670 × 10−8 W/ (m2·K4).
A 3-mm-thick glass window transmits 90 percent of the radiation between l = 0.3 and 3.0 mm and is essentially opaque for radiation at other wavelengths. Determine the rate of radiation transmitted through a 2-m * 2-m glass window from blackbody sources at (a) 5800 K and (b) 1000 K.
If a mercury thermometer is immersed in hot liquid, the mercury level goes down at first and then goes up. Explain why this happens.
A long 5-cm-diameter steam pipe passes through some area open to the wind. Determine the drag force acting on the pipe per unit of its length when the air is at 1 atm and 10°C and the wind is blowing across the pipe at a speed of 50 km/h.
Note: please use the given formula of radiation heat transfer, and use appropriate symbols and units. Formula: Qrad = eσA(T1⁴-T2⁴)
Solve the Newtons Law of Cooling problem applying first order diffential equations Angeli, who is a daughter of a famous detective, was preparing for a date with Conan Edogawa on a Sunday night. She went to her friend’s room to borrow her hair curler, but she discovered Serena’s dead body instead. Although shocked to see her friend lying on the floor, she immediately took the temperature of the body at 10:00 pm which was 95.9°F. She contacted everyone she can, and Conan was the first to come after two hours. Conan took the temperature upon his arrival which is found to be 93.7°F. He also noted the room temperature was constant at 68°F. Angeli was so curious to determine Serena’s time of death. Help her know the time that her friend died assuming the victim’s normal body temperature was 98.6°F.
The radiant flux at Earth is 1365 W/m2. Say we move towards the sun to a radius that is 1/3 the radius of the Earth's orbit. By what factor would the radiant flux increase or decrease?
(a) Deter-nine the power of radiation from the Sun by noting that the intensity of the radiation at the distance of Earth is 1370 W/m2. Hint: That intensity will be found everywhere on a spherical surface with radius equal to that of Earth's orbit. (b) Assuring that the Sun's temperature is 5780 K and that its emissivity is 1, find its radius.
