1. Air enters a converging-diverging isentropic nozzle at 10.0 MPa and 500. K with a negligible velocity and is accelerated to a Mach number of 4.50. Determine the static temperature, pressure, and density at (a) the throat, and (b) the exit. (c) Find the exit to throat area ratio.
2. Low-velocity helium enters a converging-diverging isentropic nozzle at 250. psia and 120.°F. It is accelerated to a Mach number of 2.0. at the exit. Determine the static temperature, pressure, and density at (a) the throat, and (b) the exit. (c) Find the exit to throat area ratio.
