Oil at a mass flow rate of 15,000 lbm/hr is heated in a heat exchanger from 800F to 2050F. The heat capacity of the oil can be assumed constant at 0.49 BTU/lbm-0F. The oil flows through the inside of the tubes (1.0-in. inside diameter and combined length of 400 ft). The required heat is supplied by saturated steam condensing on the outside of the tubes, keeping the temperature of the inside surface of the tubes at a constant value of 2150F. Calculate:
a. The total rate of heat transfer, in BTU/hr.
b. The total surface area for heat transfer, in ft^2.
c. The logarithmic mean temperature difference, in 0°F.
d. The heat-transfer coefficient based on the logarithmic mean temperature difference, in BTU/hr-ft^2-0F.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

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.
