Mechanical Engineering

A converging-diverging nozzle is designed to operate with anexit Mach number of 2. The nozzle is supplied from an air reservoirat 600 kPa and temperature is 300 K. The throat area of the nozzleis 5 cm2.
Determine:

(a) The ratio of exit-to-throat area and exit area.
(b) Given the area ratio in part (a), find the range of backpressure over which the nozzle is choked. What is the criticalpressure and design pressure?
Also, calculate the mass flow rate when the nozzle is choked and atdesign conditons.
(c) Determine the mass flow rate for a back pressure of 450 kPa and500 kPa.
(d) Determine the mass flow rate for a back pressure of 0kPa.
(e) Plot pressure variation along centerline of nozzle and mark allthe points (back pressures) on it.
(f) Use excel sheet to plot mass variation Vs back pressures andmark all points on it.
