Si sessions: sunday 4:00-5:30pm, tuesday 6:00-7:30pm session 8. Most people define stress" as pursuing a degree in engineering. Engineers define stress" as force divided by area. - anonymous. 1st law for a control volume: a heat exchanger is used to cool an air flow from 800 k to 360 k, both states at 1 mpa. The coolant is a water flow at 15 c, 0. 1 mpa. If the water leaves as saturated vapor, find the ratio of the mass flow rates mwater/mair: two air flows are combined to a single flow. Flow one is 1 m^3/s at 20 c and the other is 2 m^3/s at 200 c both at 100 kpa. They mix without any heat transfer to produce an exit flow at 100 kpa. Neglect kinetic energies and find the exit temperature and volume flow rate: a steam turbine receives water at 15 mpa, 600 c at a rate of 100 kg/s.
