Assumptions The tank is insulated so that no heat is transferred. Analysis a For liquids, the kinematic viscosity decreases with temperature.

The EES Equations window is printed below, followed by the 32h tabulated and plotted results. Discussion Note that the drag force acting on the pipe in this case is independent of the pipe diameter.

The viscosity of the fluid is to be determined. Since we jechanics a two-phase mixture of a pure substance at a specified temperature, the vapor pressure must be the saturation pressure at this temperature.

Chapter 2 Properties of Fluids Solution A circular disk immersed in oil is used as a damper, as shown in the figure. Analysis When air is completely evacuated, the vacated space is filled with water vapor, and the tank contains a saturated water-vapor mixture at the given pressure. Chapter 2 Properties of Fluids C Solution We are to discuss the sign of the coefficient of compressibility and the coefficient of volume expansion.

Analysis Thermal energy is the sensible and latent forms of internal energy.

Now some nitrogen is allowed to escape, and the temperature and pressure of nitrogen drop to new values. In common terminology, thermal energy is referred to as heat. Chapter 2 Properties of Fluids Solution The velocity profile for laminar one-dimensional flow between two parallel plates is given.

The number of moles and the mass of helium are to be determined. Therefore, the coefficient of compressibility of an ideal gas is equal to its absolute pressure, and the coefficient of compressibility of the gas increases with increasing pressure. Chapter 2 Properties of Fluids Solution Air in a partially filled closed water tank is evacuated.


The drop is very small in this case because of the large diameter of the tube.

Beware, some other provider is not instant. Assumptions 1 There are no impurities in the kerosene, and no contamination on the surfaces of the glass tube. Assumptions 1 The thickness of the oil layer between the disks is constant.

Analysis In the flow of a liquid, cavitation is the vaporization that may occur at locations where the pressure drops below the vapor pressure. The percent increase in density of the gas when compressed at a higher pressure is to be determined. Chapter 2 Properties of Fluids C Solution We are to compare the energies of flowing and non-flowing fluids. The gage pressure inside the bubble is to be determined. Assumptions At specified conditions, helium behaves as an ideal gas.

The change in the density of the refrigerant is to be determined. Tire Analysis The initial and final absolute pressures in the tire are 0. Answered Dec 22, Analysis The capillary effect is the rise or fall of a liquid in a small-diameter tube inserted into the liquid.

Assumptions 1 The solid particles are distributed uniformly in water so that the solution is homogeneous.

Assumptions 1 The inner cylinder is completely submerged in oil. Chapter 2 Properties of Fluids Solution A clutch system is used to transmit torque through an oil film between two identical disks.

A relation for friction drag force exerted on the pipe and its numerical value for water are to be determined. Discussion Air and many other gases at room temperature and pressure can be approximated as ideal gases without any significant loss funddamentals accuracy.

For example, on a dry day low relative humiditythe partial pressure of water vapor in the air is less fundmaentals the vapor pressure of water. It is caused by the attractive forces between the molecules. Skip to main content. A relation is to be developed for the specific gravity of the suspension in terms of the mass fraction Csmass and volume fraction Csvol of the particles.



Discussion An example of an intensive property is temperature. Analysis The coefficient of compressibility of a fluid cannot be negative, but the coefficient of volume expansion can be negative e.

During phase change processes between the liquid and vapor phases of a pure substance, the saturation pressure and the vapor pressure are equivalent since the vapor is pure. Analysis A flowing fluid possesses flow energy, which is the energy needed to push a fluid into or out of a control volume, in addition to the forms of energy possessed by a non-flowing fluid.

Therefore, the value determined is valid at the temperature of the liquid. Analysis The coefficient of volume expansion represents the variation of the density of a fluid with temperature at constant pressure.

Assumptions 1 The inclined surface is plane perfectly flat, although tilted. Discussion We must be careful to use absolute temperature K or Rnot relative temperature oC or oF. Assumptions 1 There are no impurities in mercury, and no contamination on the surfaces of the glass tube.

Not all cavitation is undesirable. Discussion Note that the vapor pressure increases with increasing temperature, and thus there is a greater danger of cavitation at higher fluid temperatures. The higher the pressure, the higher the saturation or boiling temperature. Assumptions 1 At specified conditions, air behaves as an ideal gas.

Chapter 2 Properties of Fluids Solution The density of seawater at the free surface and the bulk modulus of elasticity are given.
