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.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
