Assignment 10, Question 3, Problem Book #198
Problem Statement
Consider a Brayton cycle with a regenerator. The regenerator has an effectiveness of 75%.
The compressor inlet conditions are 1.2 bar and 300 K and the mass flowrate is 4.5 kg/s. The
compressor outlet pressure is 9 bar. Both the compressor and turbine consist of a single
isentropic stage. What minimum power output must be achieved before the regenerator
begins to have a benefit? Use an air-standard analysis.

- Aircraft B is traveling at a steady speed of VB = 400 mi/hr at an altitude of 6000 ft. Meanwhile, when aircraft A is at an altitude of 10,000 ft, the line connecting A to B lies in the vertical plane of B's flight path and forms an angle of 0 = 30 degrees with the vertical. Assuming A maintains a constant velocity, find the speed required for a collision to occur. Additionally, calculate the time it would take for the collision to happen after both aircraft reach the described positions, provided no evasive measures are taken.
