For the system described below, given that all of the devices are of the same type, and using the definitions presented in the discussion of the Banker’s Algorithm, answer these questions:
a. Calculate the number of available devices.
b. Determine the remaining needs for each job in each system.
c. Determine whether each system is safe or unsafe.
d. If the system is in a safe state, list the sequence of requests and releases that will make it possible for all processes to run to completion.
e. If the system is in an unsafe state, show how it’s possible for deadlock to occur.
This system has 16 devices.

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.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
