The conductive tissues of the upper leg can be modeled as a 35-cm-long, 16-cm-diameter cylinder of muscle and fat. The resistivities of muscle and fat are 13 Ωm and 25 Ωm, respectively. One person's upper leg is 82% muscle, 18% fat. The resistivity of the whole leg will be a weighted average of...
The figure shows the cycle for a heat engine that uses a gas having gamma =1.25. The initial temperature is T1=300K, and this engine operates at 20 cycles per second.
a.) What is the power output of the engine?
b.) What is the engine's thermal efficiency?
