Temperature of hot tube is 102 F
We know heat transfer due to convection is given by
Answer:
The cult of personality that surrounded Joseph Stalin in the Soviet Union led soviet citizens to believe that there was undisputed support for Stalin both among the government and the common people. In turn, this fueled self-censorship and made political change harder. This cult of personality was achieved through propaganda and censorship, as the Communist Party had control of all mass media. This desire to make himself a "god-like" figure was also an attempt to increase acceptance of communism among the people and to boost morale.

Answer:
Explanation:
1) Resolution and uncertainty of both ADC ranges
a) Resolution (for +/- 5 mV range) = 5 mV / 2n where n = number of bits of ADC
Resolution = 5 mV / 28 = 5 mV / 256 = 0.0195 mV ..................1
uncertainty (for +/- 5 mV range) = +/- 0.5*resolution = +/- 0.5*0.0195 mV = 0.00975 mV ..........2
b) Resolution (for +/- 5 V range) = 5 V / 2n where n = number of bits of ADC
Resolution = 5 mV / 28 = 5 V / 256 = 0.0195 V = 19.5 mV ..................3
uncertainty (for +/- 5 mV range) = +/- 0.5*resolution = +/- 0.5*19.5 mV = 9.75 mV ..........4
2)Thermocouple sensitivity = ( Maximum output voltage - Minimum Output voltage) / (Maximum Temperature - Minimum Temperature)
Thermocouple sensitivity = (3.649mv - 0 ) / (70 - 0) = 0.0521 mV / Deg.C ............5
This is the required Thermocouple sensitivity
3) Water bath temperature is given as 57 deg.C
Hence voltage read by Thermocouple = Sensitivity*57 = 0.0521*57 mV = 2.9697 mV ........6
4)We need to use ADC with a range of +/- 5 mV range as ADC with +/- 5 V range can not do measurement as it's resolution is higher than output voltage.
ADC will measure voltage as 2.9695 mV ......................7
