3. Suppose that a digitized TV picture is to be transmitted from a source that usesa. matrix of 480 X 500 picture elements (pixels), where each pixel can take on one of 32 intensity values. Assume that 30pictures are sent per second. (This digital source is roughly equivalent to broadcast TV standards that have been adopted.)Fund the source rate R (bps).b. Assume that the Tv picture is to be transmitted over a channel with 4.5-MH2 bandwidth and a 35-dB signal-to-noiseratio. Find the capacity of the channel (bps).c. Discuss how the parameters given in part (a) could be modified to allow transmission of colorTv signals withoutincreasing the required value for R

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

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.
