Chegg Consider the pulse signals
(t) ={A, 0 ≤ t ≤ T , and 0 otherwise.
A filter matched to this signal has the impulse response:
h0(t) = s(t0 − t) = {A, 0 ≤ t0 − t ≤ T or t0 − T ≤ t ≤ t0 and 0 otherwise,
where the parameter t0 will be fixed later. We note that if t0 < T, the filter will be noncausal, since it will have nonzero impulse response for t < 0.
The response of the filter to s(t) is .

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

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.

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
