Answer:
LTI system is stable if Impulse response is finite.
so the correct answer is "b"
(b) h2(t) = e-r cos(2t)u(t)
Answer:
The Reynold Number is 146415.34
Explanation:
The density of ethyl alcohol = ρ = 789 kg/m^3
The dynamic viscosity of ethyl alcohol = μ = 0.001095 kg/m.s
Velocity = V = 4 m/s
Diameter of pipe = D = 2 in = 0.0508 m
The Reynold's number (Re), will be:
Re = ρVD/μ
Re = (789 kg/m^3)(4 m/s)(0.0508 m)/(0.001095 kg/ms)
<u>Re = 146415.34</u>
Answer:
-50.22kJ
Explanation:
Given:
Initial state Temperature =300k
Pressure 1= 150kPa
Pressure 2 = 800kPa
Volume 1 = 0.2m^3
Work done = Pressure 1 × Volume 1 × (inverse of pressure 1 ÷ pressure 2)
= 150kPa × 0.2m^3 × (inv 150 kPa ÷800 kPa)
= - 50.22kJ
