Textbook Question
Chapter 19, Problem 19.1P
Of the metals listed in Table 19-1, which are the most and least conductive?
Expert Solution & Answer
To determine
The most and least conductive metal from the table 19-1.
Answer to Problem 19.1P
The most conductive metal from table 19-1 A is silver and the least conductive metal is gallium.
Explanation of Solution
Conductivity is the properties of the material by which it can be determined how much an electric charge or heat is passing through the material. A conductor has very little amount of resistance. Materials can be classified into metals, non-metals, semiconductors and insulators. Among these metals are the most conductivity and insulators like (ceramics, woods and plastics) have very little conductivity.
From the given table 19-1 A the silver (Ag) has the highest value of conductivity and gallium (Ga) has the least value of conductivity. So, silver is most conductive and Gallium is the least conductive.
The most conductive metal from table 19-1 A is silver and the least conductive metal is gallium.

Assignment 10, Question 4, Problem Book #202
Problem Statement
An ideal Brayton cycle with a two-stage compressor, a two-stage turbine, and a regenerator
operates with a mass flow rate of 25 kg/s. The regenerator cold inlet is at 490 K and its
effectiveness is 60%. Ambient conditions are 90 kPa and 20°C. The intercooler operates at
450 kPa and the reheater operates at 550 kPa. The temperature at the exit of the combustion
chamber is 1,400 K. Heat is removed in the intercooler at a rate of 2.5 MW and heat is added
in the reheater at a rate of 10 MW. Determine the thermal efficiency and the back work
ratio. Use a cold air standard analysis with cp = 1.005 kJ/(kg K) and k = 1.4.

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.
