Fluid mechanics is the branch of physics that studies fluids (liquids‚ gases‚ and plasmas) and the forces on them. Fluid mechanics can be divided into 1) fluid statics‚ the study of fluids at rest; 2) fluid kinematics‚ the study of fluids in motion; 3) fluid dynamics‚ the study of the effect of forces on fluid motion. Fluid Mechanics Overview Fluid is a substance that is capable of flowing. It has no definite shape of its own. It assumes the shape of its container. Liquids and gases are

Although different in many respects‚ liquids and gases have a common characteristic in which they differ from solids; they are fluids‚ lacking the ability of solids to offer permanent resistance to a deforming force. Fluids flow under the

Radiator fluid Coolant Radiator fluid is an essential unit of the auto since it shields the motor from the solidifying harm. At the point when the water gets changed over into ice‚ it represents an issue for the auto. Liquid catalyst is really the warmth exchange liquid which is utilized to ensure the solidifying. In both the sunlight based water radiators and the HVAC chillers it is utilized. Concoction are added to the water keeping in mind the end goal to keep the solidifying. Liquid catalyst

Chapter 3 Fluid Statics: Definitions Statics: ∑F = 0. In statics we have only pressure as surface force and weight as body force. Thus‚ when fluids are still‚ the pressure is balanced by the fluid weight. No relative motion between adjacent fluid layers. Shear stress is zero Only _______ can be acting on fluid surfaces Gravity force acts on the fluid (____ force) Applications: Pressure variation within a reservoir Forces on submerged surfaces Buoyant forces 9/4/2013 1 Pressure Pressure is defined

I. Lubricants selection and Application A.Viscosity Most important property of any lubricant is viscosity. A common mistake when selecting a grease is to confuse the grease consistency with the base oil viscosity. Because the majority of grease-lubricated applications are element bearings‚ one should consider viscosity selection for those applications. While most would not use an EP 220 gear oil for an oil-lubricated electric motor bearing‚ many people will use a grease containing that same oil

Solutions (Week-01) Chapter-01 1-12 A plastic tank is filled with water. The weight of the combined system is to be determined. Assumptions The density of water is constant throughout. Properties The density of water is given to be = 1000 kg/m3. Analysis The mass of the water in the tank and the total mass are mw =V =(1000 kg/m3)(0.2 m3) = 200 kg mtotal = mw + mtank = 200 + 3 = 203 kg Thus‚ 1-14 The variation of gravitational acceleration above the sea level is given as

withdrawal of urine. Straight catheters are used for intermittent withdrawals; indwelling (Foley) catheters are inserted and retained in the bladder for continuous drainage of urine into a closed system. Purpose Intermittent catheterization is used for the following reasons:• To obtain a sterile urine specimen for diagnostic evaluation; to empty bladder content when the patient is unable to void (urinate) due to urinary retention‚ bladder distention‚ and obstruction‚ or to measure residual urine after
