Challenge Problems
Push your limits with challenges.
Question 1
A supersonic jet is observed to have a converging diffuser with an initial pressure of 2 atm and a final pressure of 3 atm. If the initial velocity is 250 m/s, how much does the velocity decrease after passing through the diffuser?
💡 Hint: Focus on applying the ideal gas law and the conservation of mass.
Question 2
Calculate the isentropic efficiency of a nozzle if it allows a gas to increase speed from 40 m/s to 100 m/s while the ideal speed calculated is 120 m/s.
💡 Hint: Use the kinetic energy formula for calculation.
