Many patients get concerned when a test involves injection of a radioactive material. For example for scanning a gallbladder, a few drops of Technetium-99m isotope is used. However, it takes about 24 hours for the radiation levels to reach what we are exposed to in day-to-day activities. Below is given the relative intensity of radiation as a function of time. t(hrs) 0 3 9. R 1.000 0.891 0.708 0.562 0.447 0.355 The relative intensity is related to time by the equation R = A e^(Bt). Find the constant A by the least square method.(correct to 4 decimal places)

12. A piece of copper wire is initially at 150 C. We now expose this wire to air at 38 C. Find a) the rate of heat transfer at the moment of exposure and b) compare this rate of heat transfer to the rate of heat transfer from thermal radiation at the moment of exposure. Data: For copper at 150 C; k = 374 W/m-K, c = 381 J/kg-K, p = 8938 kg/m², ɛ = 0.8. The heat transfer coefficient is h = 5 W/m²-K. [Ans.: Initial heat loss is 64% due to radiation and 36% due to convection].

Molten metal at 2000 C is poured using crucible. The liquid metal jet has a diameter of 3 mm with an insulation shield of 5 cm diameter. There is a slit of 30 degrees around the insulation shield. The temperature inside the room is 30 C and the shield is 700 C. Assuming black bodies, find the net heat transfer between jet and shield, jet and room, shield and the room. One of the steps is wrong A) Resistance network is required to be built B) To find the view factor between metal and shield , ratio of the angles is used C) View factors are one of the most important steps to solve the problem D) None of the above E) Slit doesnot participate in radiation
