P.1.
assume you have built a 4-bit full adder successfully. how many bits in the results?
how to display the results in decimal on two 7-segment displays? draw the
diagram with pin-out details. you can use the chip 74ls83 for the 4-bit full adder.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
