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.
