A piston-cylinder device is filled to 1 m3 with 0.6 kg of argon at 27 °C. The piston moves by changing its loads, until the volume is twice its initial magnitude. During this process, the argon temperature remains constant. Calculate the final pressure on the device.

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)
