A system at rest is subjected to a unit step input U(t) . Its response is given by
(a) Write the input-output differential equation for the system.
(b) What is its transfer function?
(c) Determine the damped natural frequency, undamped natural frequency, and the damped ratio.
(d) Write the response of the system to a unit impulse and sketch it.
An air heater for an industrial application consists of an insulated, concentric tube annulus, for which air flows through a thin-walled inner tube. Saturated steam flows through the outer annulus, and condensation of the steam maintains a uniform..

An electric immersion heater, 10 mm in diameter and 300 mm long, is rated at 550 W. If the heater is horizon- tally positioned in a large tank of water at 20°C, estimate its surface temperature. Estimate the surface temperature if the heater is ac..
the diameter of the hollow core of a solid-propellant grain remains axially uniform during burning. the length is 5 m
Exhaust (assumed to have the properties of standard air) leaves the 4-ft-diameter chimney shown in Fig. with a velocity of 6 ft/s. Because of the wind, after a few diameters downstream the exhaust flows in a horizontal direction with the speed of ..
A rigid vessel of capacity 0.6 m3 contains dry saturated steam at 4.0 bar. The vessel is cooled until the pressure is reduced to 2.0 bar, Calculate; a) the mass of steam in the vessel.
a cold water pipe temperature is inside a room of 75 f if the cold water temperature in the pipe is 50 f. what is the
Steam enters a long, horizontal pipe with an inlet diameter of D1 = 12 cm at 1 MPa and 300°C with a velocity of 2 m/s. Farther downstream, the conditions are 800 kPa and 250°C, and the diameter is D2 = 10 cm
