Ahydraulic turbine that generates 10mw of power is tested with the of a 1: 8 model, which operates at the same angular velocity as the prototype. assume that the efficiencies of both the model and the prototype are the same 1. calculate the power of the prototype 2. find load ratio (hp / hm) 3. find the flow relation (qp/ qm)

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.

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

Asimple rankine cycle uses water as the working fluid. the water enters the turbine at 10 mpa and 480c while the condenser operates at 6 kpa. if the turbine has an isentropic efficiency of 80 percent while the pump has an isentropic efficiency of 70 percent determine the thermal efficiency
