Chapter 6, Problem 6.150EP

Momentum Transfer. Answer the ff.

A Russian submarine crashs, loses control and runs aground at the bottom of the sea. The pressure,at atm, to which the submarine gets subject ed when it ran aground at a depth of 100 meters is?(For seawater take that density is worth 1000 kg/m³)

Find the specific volume (m3/kg) for water at 500 kPa, 300 °C

urgent..

Q2/ Determine whether the state of the following water system is compressed liquid, mixture of saturated liquid and saturated vapor, or superheated vapor. (a) T=100°C, P=3.0MPA (b) T=300°C, P=100kPa (c)T=100°C, v=1.6m'/kg (d) P=0.2MPA, u=700KJ/kg

Q3: Ten kg of water at 40°C: 1. Experiesces a tempersture increase of 10 K. What is (AU, in kl? 2. Experiences a change in elevation (Ah). The change in potential energy (AE») is the same as (AU) for part (1). What is (Ah), in meters? 3. Is accelerated from rest to final velocity (u). The change in kinetic energy (AEx) is the same as (AU) for part (1). What is u, in m-s Co for water= 4.18 kl-kgc

Q4: Find the force when 60 kg of blood is given upward of about 0.1s, in a velocity nearly 1 m/s.

Patm 1. Initially; the piston sits on the stops and the linear spring exerts no force, the specific volume is 0.05 m /kg and the pressure is 125 kPa. Atmospheric pressure is 100 kPa, mass of the piston is 102 kg, and area of the piston is 200 cm?. The linear spring exerts a force on the piston in such a way that the specific volume becomes 0.08 m'/kg when the pressure reaches 200 kPa. Heat is transferred to the water until its temperature is 115 °C. Calculate work and heat transfer, showing the process on a P-v plot. Hint: In the final stage, the temperature is 115°C, but the pressure is not given. You need to find P and v using the tables and P-v plot.

E3.1. You must use the property data from the tables in the Appendix of your text to do this problem. The figure below illustrates a pressure cooker with the pressure relief valve removed. atm- 100 kPa V= 2 liter bottom 5% is filled with liquid water . The pressure cooker has an internal volume of V = 2 liters. Because the relief valve is removed, the contents are initially at atmospheric pressure, Patm = 100 kPa. The pressure cooker contains water in a two-phase state. The bottom 5% of the volume of the vessel is filled with liquid water while the remainder of the vessel contains water vapor. a) Determine the initial temperature of the water in the cooker. b) Determine the quality and specific volume of the water initially in the cooker. c) Sketch by hand a T-v diagram and label the initial state of the water (state 1).
