A controlled process is described by the closed-loop transfer function G(s). G(s) = K(s + 1)/2s^2 + (K-1)s + (K-1)
What values of K will stabilize the process?
(A) K < 1
(B) K > 1
(C) K > 0.75
(D) K > 0

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
