Liquid water at 200kpa and 15°c is heated in a chamber by mixing it with superheated steam at 200kpa and 150°c. liquid water enters the mixing chamber at a rate of 4.3kg/s, and the chamber is estimated to lose heat to the su air at 20°c at a rate of 1200 kj/min. if the mixture leaves the mixing chamber at 200kpa and 80°c determine (a)the mass flow rate of the superheated steam and (b) the rate of entropy generation during this mixing process.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

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.

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
