A comparator circuit works under those conditions [X is (a a) Write the Boolean expression.
b) Draw the logic circuit.
c) Minimize the Boolean expression by Boolean algebra.
d) Minimize the Boolean expression by Karnaugh map.
e) Draw the logic circuit after minimizing,
f) Draw the logic circuit by using NAND gates only.

The proportional limit is always greater than the yield strength for a material. a)-trune b)- false

Acircular pipe of 30mm outside diameter is placed in an airstream at 30 c and latm pressure. the air moves in cross flow over the pipe at 20 m/s, while the outer surface of the pipe is maintained at 110 c. what is the drag force exerted on the pipe per unit length? what is the rate of heat transfer from the pipe per unit length?

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference
