Solve The following Engineering problems by programming in python:
Part 1 )
Determine the heat transfer necessary to increase the pressure of 70 percent quality
steam from 200 to 800 kPa, maintaining the volume constant at 2 m^3. Assume a
quasiequilibrium process.
Part 2)
A piston-cylinder arrangement contains 0.02 m^3 of air at 50°C and 400 kPa. Heat
is added in the amount of 50 kJ and work is done by a paddle wheel until the temperature reaches 700°C. If the pressure is held constant, how much paddlewheel work must be added to the air? Assume constant specific heats
Part 3)
Calculate the work necessary to compress air in an insulated cylinder from a volume of 2 m^3 to a volume of 0.2 m^3. The initial temperature and pressure are20°C and 200 kPa, respectively.
