Assuming that the component is made of a brittle steel material and fails under the given operating stresses, failure would occur along planes whose normal is oriented at ~ degrees from the horizontal direction. (Hint: brittle materials are susceptible to failure due to excessive normal stress) A) 6 B) 12 C) 18 D) 24 E) 57 F) 69 13. Assuming that the component is made of a ductile steel material and fails under the given operating stresses, failure would occur along planes whose normal is oriented at ~ degrees from the horizontal direction. (Hint: ductile materials are susceptible to shear failure)

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
