Part.1 Complete 3 of the 5 HW-style problems that follow (12 points): 1. (4 points) In a gear system, segments (1) and (2) are both solid 1- inch-diameter. Motor rotation speed is 100 Hz. Allowable shear stress for each shaft is 8700 PSI. Calculate (a) The rotation speed of gear E (in Hz). (b) The allowable torque TE at gear E. (c) The maximum power that can be transmitted by the gear train (No FBD required)

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

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.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
