The virial equation for nitrogen gas is PV=RT(1+4.41×10-4P). Using the virial equation of state for nitrogen at 600 K, calculate
The fugacity of nitrogen at 200 atm and 600 K. The fugacity of nitrogen at 1 atm and 600 K. The change in the Gibbs free energy caused by a compression of 1 mole of nonideal nitrogen gas at 600 K from 1 to 200 atm. The change in the Gibbs free energy caused by a compression of 1 mole of ideal nitrogen gas at 600 K from 1 to 200 atm. What is the magnitude of the contribution to (c) caused by the nonideality of nitrogen?

Answer:
The instantaneous axis of rotation=
x = 0 ; z = 8.4 ft
Explanation:
Given:
Speed of helicopter, Vo= 120 mi/h, converting to ft/sec, we have:
= 176 ft/s
Angular velociyy, w = 220 rpm, converting to rad/sec, we have:
The helicopter moves horizontally in the x direction at a speed of 120 mi/h, this means that the helicopter moves in the positive x direction at 120mi/h
To find the instantaneous axis of rotation of the main blades, we have:
Where Vc = 20.95 rad/s
Vo = 176 ft/s
= 8.4 ft
Therefore the axis of rotation=
x = 0 ; z = 8.4 ft
