1. Carbon dioxide is contained in a large tank, initially at 100 lbf/in.2, 8008R. The gas discharges through a converging nozzle to the surroundings, which are at 14.7 lbf/in.2, and the pressure in the tank drops. Estimate the pressure in the tank, in lbf/in.2, when the flow first ceases to be choked.

2. Steam expands isentropically through a converging nozzle operating at steady state from a large tank at 1.83 bar, 2808C. The mass flow rate is 2 kg/s, the flow is choked, and the exit plane pressure is 1 bar. Determine the diameter of the nozzle, in cm, at locations where the pressure is 1.5 bar, and 1 bar, respectively.
