Assuming a transition Reynolds number of 5 X 105, determine the distance from the leading edge of a flat plate at which transition will occur for each of the following fluids when u[infinity]=1 m/s: atmospheric air, engine oil, and mercury. In each case, calculate the transition location for fluid temperatures of 27oC and 77oC.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
