Three kg of air is contained at 150 degrees c and 500 kpa in a sealed, deformable device and is expanded to 150 kpa in an isothermal process. if the work done by the air in this process is 300 kj, find the net amount of new disorder created and the irreversibility of the process. what might account for the calculated irreversibility, and how could it be reduceed?

What precautions should you take to prevent injuries when dealing with heavy loads?

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
