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

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
