Large ships often have circular structures in their windshields. What is their purpose? Called clearview screens, they consist of a glass
disk that is rotated at high speed by a motor in the center of the
circle) to disperse rain and spray. If the screen has a diameter of

is 40 m/s.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
