1. A nozzle is to be designed to accelerate the flow of air from a Mach number of 0.100 to 1.00. Determine the inlet to exit area ratio of the nozzle assuming isentropic flow.
2. A diffuser is to be designed to reduce the Mach number of air from 0.90 to 0.10. Assuming isentropic flow, determine the exit to inlet area ratio of the diffuser.
