A gas of 0.7 specific gravity is flowing in a linear reser-
voir system at 150°F. The upstream and downstream
pressures are 2000 and 1800 psi, respectively. The
system has the following properties:
L 2000 ft,
k = 40 md,
Calculate the gas flow rate.
W=300 ft, h = 15 ft
= 15%
Consider an aircraft engine operating at subsonic conditions with a nozzle that has an exit area of 142in2 and a nozzle inlet/exit area ratio of 2. Engine gases flowing at 30lbm/s enter the nozzle with a pressure of 0.83 bar and avelocity of 144 m/s. The gases expand through the nozzle, exiting at the ambient pressure of 7.25 psia with a velocity of 1320 ft/s.
a) For these conditions, what is the force (in units of lbf) trasmitted to the structure holding the nozzle. Provide both direction and magnitude of the force.
b) Based on your results, comment on whether the force acting on the nozzle would hlep speed up or slow down a vehicle that used this nozzle as part of a jet propulsion system.
I mostly wanted help in part b. Thank you.
