A CO2 cartridge is used to propel a small rocket cart.
Compressed gas, stored at 35 MPa and 20C, is expanded
through a smoothly contoured converging nozzle with 0.5
mm throat diameter. The back pressure is atmospheric.
Calculate the pressure at the nozzle throat. Evaluate the
mass flow rate of carbon dioxide through the nozzle.
Determine the thrust available to propel the cart. How much
would the thrust increase if a diverging section were added to
the nozzle to expand the gas to atmospheric pressure? What
is the exit area? Show stagnation states, static states, and the
processes on a Ts diagram.
