Air at 600 kPa, 330 K enters a well-insulated, horizontal pipe having a diameter of 1.2 cm and exits at 120 kPa, 300 K. Applying the ideal gas model for air, determine at steady state (a) the inlet and exit velocities, each in m/s, (b) the mass flow rate, in kg/s, and (c) the rate of entropy production, in kW/K.
Chapter 4 – Rate I. First Determine Rate a. Actual Heart Rate is the average number of cycles in a minute i. Too Low = When symptomatic ii. Too High = Greater than 100 bpm II. Sinus Rhythm a. SA Node generates continuous series of regular pacemaking stimuli (automaticity) i. SA Node located within upperposterior wall of right atrium ii. Emits series of depolarization stimuli b. At rest, maintains a rate of 60100 bpm c. A rhythm originating in the SA Node at a rate of 60 bpm or lower is called sinus bradycardia (1 beat per second) i. Often results from parasympathetic excess d. Rhythm originating in
