Consider the differential equation x'' + 4x' + x = 2u + 3u with zero initial conditions and a unit step input, u = 1(t).a. Using the final value theorem, predict the steady state output of this system, then plot the response in Simulink to confirm your result. b. Will the steady state response of this system change if the initial conditions are non-zero.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
