QUESTION 2 a) Consider the grain supply bin as shown in Figure Q2a. The control system is to maintain the flow of grain from the storage bin to provide a constant flow rate on the conveyor. This flow depends on the height of grain in the bin, and hence the vane-type hopper valve must open or close to compensate for the variation. In this case, an actuator operates this valve to control the grain flow rate. The actuator could be a motor to adjust shaft position. Construct functional block diagram of the system in Figure Q2a. Describe the feedback element, controlled variable, manipulated variable and process variable.

You are working as an electrician in a large steel manufacturing plant, and you are in the process of doing preventive maintenance on a large DC generator. You have megged both the series and shunt field windings and found that each has over 10 M to ground. Your ohmmeter, however, indicates a resistance of 1.5 across terminals S1andS2. The ohmmeter indicates a resistance of 225 between terminals F1andF2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer.

Question 13 of 15 Determine: The figure below shows a vapor power cycle that provides process heat and produces power. The steam generator produces vapor at 500 lbf/in.², 800°F, at a rate of 8 x 104 lb/h. Seventy percent of the steam expands through the turbine to 10 lbf/in.² and the remainder is directed to the heat exchanger. Saturated liquid exits the heat exchanger at 500 lbf/in.² and passes through a trap before entering the condenser at 10 lbf/in.² Saturated liquid exits the condenser at 10 lbf/in.² and is pumped to 500 lbf/in.² before entering the steam generator. The turbine and pump have isentropic efficiencies of 85% and 89%, respectively. For the process heat exchanger, assume the temperature at which heat transfer occurs is 465°F.
