ME 3022 - HW 19 1. (More practice from Monday) A 90° elbow in a horizontal pipe is used to direct a flow of oil (SG = 0.87) upward at a rate of 40 kg/s. The cross- sectional diameter of the elbow is a constant 20 cm. The elbow discharges at A into a large holding tank where the level of oil is 1.8 m above A. The "weight" of the elbow and the oil in it is 50 kg. Determine (a) the gage pressure at the inlet of the elbow and (b) the anchoring force needed to hold the elbow stationary. Take the momentum-flux correction factor to be 1.03 50 cm 40 kg/s • at both the inlet and the outlet.

Example 1.1 Figure 1.5 shows the block diagram of a closed-loop flow control system. Identify the following elements: (a) the sensor, (b) the transducer, (c) the actuator, (d) the transmitter, (e) the controller, (f) the manipulated variable, and (g) the measured variable. In the figure above, the (a) sensor is labeled as the pressure cell. The (b) transducer is labeled as the converter. However, there are two converters: one for converting pressure to current, and another converting current to pressure for operating the actuator. The (c) actuator is labeled as the pneumatic valve. The (d) transmitter is labeled as the line driver. The (e) controller is labeled as the PLC. The (f) manipulated variable is labeled as the pressure developed by the fluid flowing through the orifice plate. The (g) measured variable is the flow rate of the liquid.

In the mid-1900s, several technological and analysis concepts came together to make the PID controller widely accepted as an effective industrial controller. Discuss in detail and evaluate the performance of a PID or three-term controllers that are widely used in a typical paper mill where there may be about 2000 control loops, and over 90% of these would be PID control loops.
A proportional controller is used to control the height of water in a tank where the water level can vary from 0 to 4.0 m. The required height of water is and the controller is to close a valve fully when the water rises to 3.9 and open it fully when the water falls to 3.1 m.
