An aluminum alloy [e = 73 gpa] cylinder (2) is held snugly between a rigid plate and a foundation by two steel bolts (1) [e = 180 gpa]. the aluminum cylinder has a length of l2 = 275 mm and a cross-sectional area of 2300 mm2. each steel bolt has a length of l1 = 335 mm and a diameter of d1 = 14 mm. the bolt has a pitch of 1 mm. this means that each time the nut is turned one complete revolution, the nut advances 1 mm. the nut is hand-tightened on the bolt until all slack has been removed from the assembly but no stress has yet been induced. determine the magnitude of the normal stress produced in the aluminum cylinder when the nut is tightened one complete turn past the snug-tight condition.

Apreheater involves the use of condensing steam at 100°c on the inside of a bank of tubes to heat air that enters at 1 atm and 25°c. the air moves at 5 m/s in cross flow over the tubes. each tube is 1 m long and has an outside diameter of 10 mm. what is the minimum value of nl needed to achieve an outlet temperature of t 75 c? what is the corresponding pressure drop across the tube bank?

Air (c-1.006 kj/kg.k, r-0.287 kj/kg.k) enters a nozzle steadily at 280 kpa and 77°c with a velocity of 50 m/s and exits at 85 kpa and 320 m/s. the heat losses from the nozzle to the surrounding medium at 20°c are estimated to be 3.2 kj/kg. determine (a) the exit temperature and (b) the total entropy change for this process. solve this problem using constant specific heats.
