Problem 6 (10 points): Suppose a certain accelerometer chip measures data in 20-bit two's complement format and stores it across three registers in the following manner: X19 X18 X17 X16 X15 X14 X13 0 X12 X11 X10 X9 X8 X7 X6 0 Register_1 Register_2 X5 X4 X3 X2 X1 X0 0 0 Register_3 where, X0 is the least significant bit and X19 is the sign bit. The accelerometer is set to output data within the range of -6g to +6g.

A. [4 points] What is the resolution of the accelerometer in terms of g (e. g., 0.43g, g/32, etc.)?

B. [6 points] If you configure your microcontroller to read only two of the three registers,

a. Which two registers should you choose?
b. "The range of acceleration that can be measured is now -4g to +4g": True or False?

c. If the speed of data transfer (in bits per second) from the accelerometer to µC is constant, the effective sampling rate will (circle one) (i) increase (ii) decrease (iii) remain the same

d. The effective signal-to-quantization noise ratio (SQNR) will (circle one) (i) increase (ii) decrease (iii) remain the same

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
