Textbook Question
Chapter 12, Problem 4RQ
Referring to Figure 12–14, assume that the normally open 2M contact located between wire numbers 23 and 29 is welded closed. Also assume that none of the motors are running. What would happen if:
- a. The number 2 push button was to be pressed before the number 1 push button?
- b. The number 1 push button was to be pressed first?

3-55 A multifluid container is connected to a U-tube,
as shown in Fig. P3–55. For the given specific gravities
and fluid column heights, determine the gage pressure at
A. Also determine the height of a mercury column that
would create the same pressure at A. Answers: 0.415 kPa,
0.311 cm
I need help answering parts a and b
Required information
Water initially at 200 kPa and 300°C is contained in a piston-cylinder device fitted with stops. The water is allowed to cool
at constant pressure until it exists as a saturated vapor and the piston rests on the stops. Then the water continues to cool
until the pressure is 100 kPa.
NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
Water
200 kPa
300°C
On the T-V diagram, sketch, with respect to the saturation lines, the process curves passing through the initial, intermediate, and final states of the water. Label the
T, P, and V values for end states on the process curves.
