A system consisting of 1 kg of H2O undergoes a power cycle composed of the following processes: Process 1–2: Constant-volume heating from p1 5 5 bar, T1 5 1608C to p2 5 10 bar. Process 2–3: Constant-pressure cooling to saturated vapor. Process 3–4: Constant-volume cooling to T4 5 1608C. Process 4–1: Isothermal expansion with Q41 5 815.8 kJ. Sketch the cycle on T– and p– diagrams. Neglecting kinetic and potential energy effects, determine the thermal efficiency

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.

Analyze the factors that influence the choice between the following pairs of processes to make the products indicated: i) sand casting versus die casting of an electric-motor housing ii) thread rolling versus machining of a bolt for high-strength application. (co3/c5)
