A piston cyfinder system containing 0. 5kg of air is compressed from a volume of 0. 35 m3 to a volume of 0. 1 m3. If the initial pressure was 150 kPa and the process can be modeled as a polytropic process with n = 1. 4, determine the change in temeprature, the change in internal energy, the work, and heat transfer. Assume air behaves as an ideal gas with constant specific heats of cp = 1. 020kJ/kg-K and cv = 0. 742 kJ/kg-K.
What is the discharge revised discharge pressure of the compressor.
Design a process for the manufacture of 10^6 kg per year of mayonnaise. the shelf life of the product is expected to be 1 year. You need to complete the following in your design.
Air in piston/cylinder at 200 kPa, 600K is expanded in a constant-pressure process to twice the initial volume (state 2). At this point, the piston is locked with a pin and heat is transferred to a final temperature of 600K. Find the work and heat..
