Problem 3 (3 points): Given a unity feedback system that has the forward transfer function Do the following: 1. Sketch the root locus; 2. Find the imaginary-axis crossing; 3. Find the gain, K, at the imaginary crossing; 4. Find the break-in and break away points; 5. Find the angle of departure from the complex poles.

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

Inadequate stores control is not an obstacle to effective work order system. (clo4) a)-true b)-false

Air enters a horizontal, constant-diameter heating duct operating at steady state at 290 k, 1 bar, with a volumetric flow rate of 0.25 m°/s, and exits at 325 k, 0.95 bar. the flow area is 0.04 m2. assuming the ideal gas model with k = 1.4 for the air, determine (a) the velocity at the inlet and exit, each in m/s, and (c) the rate of heat transfer, in kw flow rate, in kg/s, (b) the mass kg 0.3
