Nitrogen at an initial state of 300 K, 150 kPa, and 0.35 m3 is compressed slowly in an isothermal process to a final pressure of 800 kPa. Determine the work done during this process. The work done during this process is kJ

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

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.
