A CRC is constructed to generate a 4-bit FCS for a 9-bit message. The generator polynomial is X4 X3 1. a) Draw the shift-register circuit that would perform this task. b) Encode the data bit sequence 111011001 using the generator polynomial and give the codeword T(X). c) Now assume that the 7th bit (counting from the left side) in the codeword is in error and show that the detection algorithm detects the error

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
