Design a compensator to yield the following specifications: settling time 2: 86 seconds; percent overshoot 4: 32%; the steady-state error is to be improved by a factor of 2 over the uncompensated system. b. compare the transient and steady-state error specifications of the uncompensated and compensated systems. c. compare the gains of the uncompensated and compensated systems.

Fluids at rest possess no flow energy. a)- true b)- false

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
