A long thin copper rod (K = 377 W/m K) 10 mm in diameter is exposed to an environment at 22 oC. The base temperature of the rod is maintained at 150 oC. The heat transfer coefficient between the rod and the environment is 11 W/m2 K.

Determine the minimum force P to prevent the 30 kg uniform rod AB from sliding. The contact surface at B is smooth, whereas the coefficient of static friction between the rod and the wall at A is μs = 0.3.

A ventilation duct must convey 2 000 m of air per hour. The cross section of the duct is rectangular, 1 000 mm x 500. Determine the average air velocity as well as the mass flos rate if the air density is 1,2 kg/m3
