5. Air undergoes an isentropic process from state 1 to state 2, where T = 400F and p = 1 lbf/in to p2 = 10 lbf/in. Determine the temperature at state 2, in units of [F], assuming ideal gas behavior, constant specific heat values. 6. Write the general form of the Energy Rate Balance equation for a closed system. a. Place a box around your answer b. Describe each variable in the equation. 7. Write the Mass Rate Balance equation for a control volume, assuming one inlet and two outlets. a. Place a box around your answer. b. Assuming that the device operates at steady state, and the elevations of the inlet and outlet are similar, reduce the equation. Place a box around your answer. tral volume assuming one inlet and one outlet.
