P2) (50 pts.) The boiling temperature of nitrogen at atmospheric pressure at sea level (1 atm pressure) is -196°C. Therefore, nitrogen is commonly used in low-temperature scientific studies, since the temperature of liquid nitrogen in a tank open to the atmosphere will remain constant at -196°C until it is depleted. Any heat transfer to the tank will result in the evaporation of some liquid nitrogen, which has a heat of vaporization of 198 kJ/kg and a density of 810 kg/m3...

To understand how the linear momentum equation is derived from Reynolds transport theorem and to use the equation to calculate forces. The Reynolds transport theorem(DNDt)syst-aatJcvηρdVtfcsqpVdA relates the change in an extensive quantity N for a system of Lagrangian particles (the left side) to the changes in an intensive quantity η:nm, where m is the mass of the system, in a Eulerian control volume that initially...
