Textbook Question
Chapter 19, Problem 19.28PP
Forthe conditions shown in figs. 19.719- 19.10 0, complete the design of the duct system by specifying the sizes for all duct sections necessary to achieve a system that is balanced when it carries the flow rates shown. Compute the pressure at the fan outlet, assuming that the final outlets from the duct system are to atmospheric pressure. When an inlet duct section is shown, also complete its design and compute the pressure at the fan inlet. Note that there is no single best solution to these problems, and several design decisions must be made. It may be desirable to change certain features of the suggested system design to improve its operation or to make it simpler to achieve a balanced system.

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. Problem outline: 1- Find the velocity of A for the collision to happen. 2- Find the time at which the collision happens. 3- Explain the solution process with your own words. - 10,000 ft 12° 6000 ft B UBarrow_forwardDetermine the gross take-off weight of the aircraftarrow_forwardplease very urgent i need the answerarrow_forward
