A tubular heater with a black inner surface of uniform temperature Ts = 1000 K irradiates a coaxial disk. (a) Determine the radiant power from the heater which is incident on the disk, qs → 1. What is the irradiation on the disk, G1? (b) For disk diameters of D1 = 25, 50, and 100 mm, plot qs → 1 and G1 as a function of the separation distance L1 for 0 ≤ L1 ≤ 200 mm.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
