In a Dual cycle, the volume at the beginning of the isentropic compression is 0.88 L and the pressure is 1 bar. If the swept volume of the cycle is 0.81 L, the volume ratio during the constant pressure heat addition process is 2.2, the pressure ratio during the constant volume heat addition process is 1.95, the specific heat ratio is y=1.32 and the heat rejected is 446.3 kJ/kg, the work done in kJ per kg of air is: Select one: a. 450.0 O b. 705.2 O c. 621.4 d. 124.5

On a average work day more than work place firs are reorted

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

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.
