For the unity negative feedback system g(s) = k(s+6)/ (s + 1)(s + 2)(s + 5) it's known that the system is operating with a dominant-pole damping ratio of 0.5. design a pd controller so that the settling time is reduced by a factor of 3, compared with the uncompensated unity negative feedback system. compare the percentage overshoot and resonant frequencies of the uncompensated and compensated systems.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
