specific gravity
Specific Gravity
  • Is a dimensionless number
  • It is the ratio of a fluid’s density to that of Water
  • Water has a specific gravity of 1
  • A fluid with a specific gravity of 0.5 weighs 1/2 as much as the same volume of Water
specific heat
Specific Heat
  • The Amount of Heat, in number of Calories, that is required to raise the Temperature of one gram of a Liquid one degree Celsius
  • Specific Heat is also expressed as the number of British Thermal Units (BTU’s) necessary to raise the Temperature of one pound of a Liquid one degree Fahrenheit
specific heat4
Specific Heat
  • The Specific Heat of WATER is one Calorie per degree Celsius
  • One Calorie of heat must be supplied to a gram of WATER to raise the Temperature one degree Celsius
  • The Specific Heat of WATER is one BTU per degree Fahrenheit
  • One BTU of Heat must be supplied to a Pound of WATER to raise the Temperature one degree Fahrenheit
vapor pressure
Vapor Pressure
  • Is also known as the Boiling Point
  • Is the Pressure Below which a liquid at a given temperature will become a gas
  • Is the Pressure Above which a gas will become a liquid

Vapor Pressure

What is the Vapor Pressure of WATER at Sea Level ?

What is the Coldest Temperature at which you can Boil WATER?

viscosity
Viscosity
  • VISCOSITY: Property of a FLUID that tends to prevent it from Flowing when subjected to an Applied Force.
  • High-ViscosityFluids Resist Flow; Low-ViscosityFluids Flow Easily.
  • The Tenacity with which a Moving Layer of Fluid drags adjacent Layers of Fluid along with it Determines its Viscosity!

LIQUID MIXTURES
  • 1. BLEND OF INGREDIENTS: A Liquid Substance containing several ingredients combined or blended together.
  • 2. CHEMISTRY: Liquid Substance formed without Chemical Reaction: a substance consisting of two or more substances that have been combined without chemical bonding taking place

LIQUIDS WITH DISSOLVED SOLIDS
  • 1. CHEMISTRY: A Liquid Substance with One or More Solids Dissolved in it.
liquids with un dissolved solids
LIQUIDS WITHUN-DISSOLVED SOLIDS

GENERALLY

Specific Gravity of Particles

Specific Gravity of Liquid

  • A Number >1 = Particles will Displace Liquid Toward the Rotating Shaft
  • Stated Differently Particle is Centrifuged Away from the Shaft

SOLIDS, PARTICLES, & FLAKES IN LIQUIDS
  • The Behavior of a Solid, Particle, or Flake Inside a Pump Stuffing Box is Highly Dependent on its Shape.
  • The Solid’s Shape and Fluid Turbulence Pattern Inside the Stuffing Box will determine its behavior

Seal Cavity Flow Components

  • Axial flow

Driven by rotating radial surfaces like the back of the seal

  • Rotational (Angular Flow)

Developed by shaft rotation.

slide20

Rotational Flow

  • Abrasives

Driven out to the bore

  • Air

Driven in to surround the shaft
