Describe how dams and reservoirs are used in water planning
What will be an ideal response?
Dams and reservoirs collect and store water at peak rainfall periods, thus reducing flood damages. They hold water
in place for later use in irrigation or municipal water treatment for human use

How is placement of the evaporator line determined when drawing a PH diagram of an operating system?
A) The evaporator line is always drawn on the horizontal line representing 50 psia absolute pressure. B) Draw a horizontal line across the saturation curve on the constant pressure line equal to the system low side absolute pressure. C) The evaporator line can be drawn anywhere that crosses the saturation curve as long as it is a horizontal line. D) Draw a vertical line across the saturation curve on a constant enthalpy line equal to the system low side absolute temperature.
Figure P12.20 depicts a low-cost full-wave bridge rectifier with a Zener diode voltage regulator. Sketch the voltages across terminals a-b, c-d, and e- f . The transformer turns ratio is 10:1 (step down). Assume VZ = 12 V and silicon rectifier diodes.
