Air flows through a nozzle from a large vessel in which the pressure and temperature are 500 kPa and 60°C respectively. The flow through the nozzle can be assumed to be steady, isentropic and one-dimensional. Knowing that the inlet diameter of the nozzle is 20 cm, if the temperature of the air is measured to be -50°C at a particular section. Part A. Determine the velocity and the pressure of the air at this particular location. Part B. Determine the velocity and pressure of the air, when temperature further drops to -80°C as air moves along the nozzle. [Take R = 287 J/kg-K and k = 1.4]
