Question:
The Pitot-static probe used in the wind-tunnel experiment is connected to a differential pressure sensor. The sensor is made by Honeywell, model ASDXRRX010NDAA5, and has ratio metric analog output. The sensor is powered by a 5V electrical supply and its output voltage is fed to a 12-bit analogue-to-digital converter of a Microchip PIC24FV32KA301 I/P microcontroller. The 5V supply, for both the sensor and the microcontroller's ADC, is provided by a LM7805 linear regulator which has a quoted uncertainty of ±4%. Assuming the same air conditions as for the previous problem, plot the expected ADC count and uncertainty for flow velocities from zero to 30 m/s. Also, tabulate your results for velocities 5, 10, 20 and 30 m/s
