As you all know, House Atreides has been granted control of planet Arrakis, the source of the invaluable spice melange, and is preparing to take over its mining operations. As a propulsion engineer serving Duke Leto Atreides, you are tasked with ensuring the safe arrival and operation of the House's frigate fleet in this new harsh desert environment.
Arrakis presents a unique challenge with its different atmospheric pressure regarding Caladan (your original planet). This could significantly affect the performance of your frigates' rocket engines, designed initially for Caladan. Your task is to analyze the engine's performance under these new conditions.
Given the following engine parameters, determine the nozzle conditions and Specific Impulse. The success of the spice mining operation, and perhaps the fate of House Atreides, rests on your calculations.
Engine Parameters:
- Chamber pressure = 14.6 Mpa
- Chamber temperature = 4250 K
- Gas constant = 360 J/(kg K)
- Specific heat ratio; gamma = 1.3
- Ambient pressure = 71320 Pa
- Nozzle expansion ratio = 15
- Exit diameter = 2.1 m
- Mass flow rate = 3100 kg/s
- g0 = 9.81 m/s² (Arrakis gravity is very close to Earth's)
