Air passes through a jet engine nozzle operating at steadystate. The flow at the nozzle inlet has a temperature of 900° F.The nozzle inlet has an area of 5 ft2. The flow at the nozzleoutlet has a temperature of 875° F, a specific volume of 90 ft3/lb,and a velocity of 600 ft/s. The nozzle outlet has an area of 2 ft2.Model the air as an ideal gas with constant specific heats.Evaluate the specific heats at 900° F. Assume the nozzle is wellinsulated and neglect potential energy changes. Determine thevelocity in ft/s and specific volume in ft3/lb of the flow at theinlet.
