Suppose that taking the 256-point dft of fx[0]; x[1]; x[2]; : : : x[255]g yields a set 256 dft coeffcients that are mostly zero; in particular, suppose that there are only three nonzero dft coeffcients: x[0] = 512, x[8] =-64j and x[248] = 64j. find an equation for the n-th time-domain value x[n] that is valid for n = 0; : : : ; 255.

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
