Suppose one of your classmates claims that the following boolean expressions represent the conversion from 4-bit Gray code to 4-bit binary numbers:
B3 = G3
B2 = G3 ⊕ G2
a. How many flip-flops would be required?
b. Sketch the circuit needed to implement this counter.
An ion exchange column is designed to "soften" water. In a particular application, the bed is filled with particles that are approximately spherical, with dp = 4 mm, and voidage epsilon = 0.30. The bed fills a cylinder with diameter 0.2 m, and is 1.0..
Air enters the compressor of a turbofan engine at –20°C and 60 kPa, with a flow rate of 95 kg/s and speed of 170 m/s. At the compressor exit, pressure is 1830 kPa, temperature is 455°C, and speed is 134 m/s. The aircraft is pitched up so that the cen..
A piston-cylinder device contains 25 ft3 of nitrogen at 40 psia and 700°F. Nitrogen is now allowed to cool at constant pressure until the temperature drops to 200°F. Using specific heats at the average temperature, determine the amount of heat los..
You must design a device that will remove the balls from the bucket, and deposit them into the box. You will have 60 seconds to remove balls.
