For an isentropic flow along a nozzle, at location A, the static temperature and pressure were measured to be 320 K and 5 bar. What will be the static pressure at the location where the static temperature is 500 K? (Given η = 1.4)

Nozzle Theory and Thermodynamic Relations topics include: ideal rocket, thermodynamic relations summary, nozzle configurations, isentropic flow through nozzles, real nozzles, four performance parameters, nozzle alignment and variable thrust.

Nozzle theory and thermodynamic relations are used to evaluate and compare the performance of different rocket systems. These relations can predict operating parameters for any system that uses the thermodynamic gas expansion in a supersonic nozzle. 

A nozzle is a device that increases the velocity of a fluid at the expense of pressure. The cross sectional area of a nozzle decreases in the flow direction for subsonic flows and increases for supersonic flows. 
The efficiency of a nozzle is the ratio of the actual velocity of the fluid in it to the theoretical velocity. In thermodynamics, it is the ratio of energy supplied to the blades per kg of steam to the total energy supplied per stage per kg of steam. 
In a nozzle, enthalpy decreases as the velocity and kinetic energy increase. This most often results in a decrease in U and therefore in temperature and a drop in the PV product.
