100 kg/min of supercritical nitrogen at T = 135 K and P = 64 bar flows into a chamber, as illustrated in Figure 5-15. The sudden increase in diameter leads to a large pressure drop; the pressure in the chamber is P = 1 bar. The chamber has no moving parts, operates at steady state, and can be modeled as perfectly insulated. Find the flow rates of nitrogen liquid and vapor leaving the chamber.
