Pressure sensor rated at 0-500 psi and has an output of 0-10 Volts DC (10 V correspond to 500 psi) .it is connected to PLC analog input module that is 12 Bits if the PLC read the
Analog input as 8B3 HEX, what is the pressure in psi and the resolution in psi for the
System.​

Apipe with an outside diameter of 15 cm is exposed to an ambient air and surrounding temperature of -20°c. the pipe has an outer surface temperature of 65°c and an emissivity of 0.85. if the rate of heat loss from the pipe surface is 0.95 kw per meter of length, the external convective heat transfer coefficient (h) is: (a) 12.5 w/m"k (b) 18.6 w/mk (c) 23.7 w/mk (d) 27.9 w/mk (e) 33.5 w/mk
