For the silicon chip of Example 3.5, determine the rate of entropy production, in kW/K. What is the cause of entropy production in this case? 7.43 At steady state, a 15-W curling iron has an outer surface temperature of 90°C. For the curling iron, determine the rate of heat transfer, in kW, and the rate of entropy production, in kW/K.
Example 3.5:
A silicon chip measuring 5 mm on a side and 1 mm in thickness is embedded in a ceramic substrate. At steady state, the chip has an electrical power input of 0.225 W. The top surface of the chip is exposed to a coolant whose temperature is 20°C. The rate of energy transfer by heat between the chip and the coolant is given by Q = -hA(Tb - Tf), where Tb and Tf are the surface and coolant temperatures, respectively, A is the surface area, and If heat transfer between the chip and the substrate is negligible, determine the surface temperature of the chip, in °C.
Suppose we wish to represent an n-vertex graph G using the edge list structure, assuming we identify the vertices with the integers in the set {0,1,...,n?1}.

A suggested approach is to begin with a workstation running a web browser and trace a connection to a public web server (i.e. facebook; eBay; etc).
Design (draw the diagram) a Moore machine that performs a parity check on the input string (string of 0 and 1): that is, the output string ends in 1 if the total number of 1-bits in the input string is odd and 0 if the total number of 1-bits in th..
