Question: A 100-cm long aluminum bar, with perfectly insulated sides, has its ends kept at constant temperatures of 0 oC and 100 oC from start until steady state conditions are reached.
a. Derive an analytical expression for the temperature distribution along the length of the rod and for various time values.
b. Write a script using MATLAB® and plot the temperature distribution along the length of the rod for progressive time intervals. Using the plot approximately determine the maximum time after which steady state is reached.
A voltage signal consists of a pure sine wave of amplitude 10.0 V at 180 Hz. This signal is sampled digitally at a sampling frequency of 200 Hz. 128 data points are taken.
A stationary gas turbine power plant operates on a simple ideal Brayton cycle with air as the working fluid. The air enters the compressor at 95 kPa and 290 K and the turbine at 760 kPa and 1100 K. Heat is transferred to the air at a rate of 35,00..
