Note that the density increases during cooling, as expected. Assumptions The gas behaves an ideal gas. Discussion Note that the damping torque and thus damping power is inversely proportional to manial thickness of oil films on either side, and it is proportional to the 4th power of the radius of the damper disk.
Discussion A good way to remember this is that a car engine solutoon much harder to start in the winter because the oil in the engine has a higher viscosity at low temperatures.
Discussion Flow energy is not to be confused with kinetic energy, even though both are zero when the fluid is at rest.
Analysis The magnitude of the capillary rise solutioh two large parallel plates can be determined from a force balance on the rectangular liquid column of height h and width w between the plates.
Film thickness varied from 0. A pressure cooker uses this principle. If link above is not working, You can use this direct link: It is caused by the attractive forces between the molecules.
By opening and using this Manual the user agrees to the following restrictions, and if the recipient does not agree to these restrictions, the Manual should be promptly returned unopened to McGraw-Hill: Chapter 2 Properties of Fluids Solution We are to investigate the effect of oil film thickness on the transmitted torque.

Discussion Note that the power required to overcome shear forces in a viscous fluid greatly depends on temperature. Learn More at wikibuy. The viscosity of the fluid is to fouid determined.
For example, on a dry day low relative humiditythe partial pressure of ,anual vapor in the air is less than the vapor pressure of water. The total energy of a flowing fluid consists of internal, kinetic, potential, and flow energies. Analysis The internal energy of a system is made up of sensible, latent, chemical, and nuclear energies. The capillary drop of mercury in the tube is to be determined.
The power required to maintain this motion and the reduction in the required power input when the oil temperature rises are to be determined. Discussion Partial pressure is not necessarily equal to vapor pressure. The force that needs to be applied in the horizontal direction when the block is dry, and the percent reduction in the required force when an oil film is applied on the surface are to be determined.
Problems are randomized to prevent sharing of answers an may also have a “multi-step solution” which helps move the students’ learning along if they experience difficulty. The increase in the density of water is to be determined.
Assumptions 1 The solid particles are distributed uniformly in water so that the solution is homogeneous. Analysis Substituting the numerical values, the surface tension is determined from the surface tension force relation to be F 0.
The amount of air that needs to be added to the tire to mechanica its pressure to the recommended value is to be determined. Analysis The coefficient of compressibility represents the variation of pressure of a fluid with volume or density at constant temperature.
Analysis Consider solid particles of mass ms and volume Vs dissolved in a fluid of mass mf and volume Vm. Assumptions At specified conditions, helium behaves as an ideal gas.
The maximum water temperature to avoid the danger of cavitation is to be determined. Chapter 2 Properties of Fluids Solution The minimum pressure in a piping system to avoid cavitation is to be determined.
Discussion Note that the vapor pressure increases with increasing manuap, and thus the risk of cavitation is greater at higher fluid temperatures. In general, liquids have higher dynamic viscosities than gases. Discussion Note that the drag force acting on the pipe in this case is independent of the pipe diameter. Viscosity is caused by the cohesive forces between the molecules in liquids, and by the molecular collisions maanual gases.
Chapter 2 Properties of Fluids Solution A clutch system is used to transmit torque through an oil film between two identical disks. Discussion This may not seem like a large temperature increase, but if the tire is fyndamentals at 20oC Chapter 2 Properties of Fluids Solution A relation for the variation of density with elevation is to be obtained, the density at 7 km elevation is to be calculated, and the mass of the atmosphere using the correlation is to be estimated. This tool looks for lower prices at other stores while you shop on Amazon and tells you where to buy.
Easily convert one document format to another through the use of dynamic API-based file parameters. Discussion We must be careful to use absolute temperature K or Rnot relative temperature oC or oF.
Fundamentals and Applications Cengel Maual 4th Edition. Mechankcs maximum diameter of the ball is to be determined, and the calculations are to be repeated for aluminum. Chapter 2 Properties of Fluids Solution The specific gravities of solid particles and carrier fluids of a slurry are given. It is due to the internal frictional force that develops between different layers of fluids as they are forced to move relative to each other. Assumptions 1 There are no impurities in mercury, and no contamination on the surfaces of the glass tube.
Discussion Surface tension is the cause of some very interesting phenomena such as capillary rise and insects that can walk on water. 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. The change in temperature anx exactly half of that of the previous problem, as expected.
If the fluid is moving as a rigid body, but not flowing, it may also have kinetic energy e. Assumptions 1 The thickness of the oil film is uniform.
