Determine the output pressure of a compressor operating with the following data: i. Actual power required to drive the compressor is 20 kW.
ii. Overall efficiency of the compressor is 75%
iii. Compressor delivers four standard mº/min.
iv. Compressor inlet pressure is 100 kPa.​

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite
