Problem 3. (15pts) Complete the following questions by analyzing the Water Phase Diagram.a) Water is heated from its initial condition (7=60°C, P=0.8atm) under constant pressure to thewater vapor equilibrium curve. Specify the temperature and pressure at that equilibrium point.b) Water is depressurized from its initial condition (7=60°C, P=0.8atm) under constant temperatureto the water vapor equilibrium curve. Specify the temperature and pressure at that equilibriumpoint.c) You are boiling water near the top of Longs Peak (P=0.6atm). At what temperature of the liquidwater will the water begin to boil?d) While boiling water on Longs Peak, is it possible to heat the liquid water to a temperature aboveyour answer in part c)? Explain.

The objective of the question is to understand the phase changes of water under different conditions…

In the Figure below, a pool of liquid sodium is sitting in open atmosphere (and somehow not exploding from the moisture in the air) and an absolute pressure measurement device. The measurement device reads an absolute pressure of P2 at the depth of L in the pool. dP a) Calculate the pressure gradient (-) b) Using Excel plot the pressure distribution from the P2 and P1. Figure 1: A 2-D pool of Sodium on Earth that magically is keeping all of it's liquid inside even though it has no front and back sides.

An initially empty tank on Earth is being filled with water so that the height of the water in the tank increases at a steady rate. Which one of the following graphs best describes the gauge pressure P at a point on the bottom of this tank as a function of time t during the filling process? Assume the tank starts filling at time t = Os and that the top of the tank is open to the atmosphere. The atmospheric pressure does not change during the process. The water in the tank does not overflow or reach the top of the tank during this process. A) D) P B)
Q1: In Fig. 1 all fluids are at 20°C. Gage A reads 350 kPa absolute. Determine (a) the height h in cm; and (b) the reading of gauge B in kPa absolute. Air, 180 kPa abs h Water 80 cm Mercury Fig. 1
For the open tank, the piezometers attached on the side, containing two different immiscible liquids, as shown in the figure, find the elevation of the liquid surface in piezometer A.
Water flows steadily from a nozzle into a large tank as shown below. The water then flows from the tank as a jet of diameter d. (a) Using the piezometer tube shown, determine the flow rate through the nozzle. (b) Using the flow rate determine the value d if the water in the tank remains constant. Viscous effects are negligible.
Carefully explain the solution. Thank you.
