BRILLIANT PTOA READERS AND STUDENTS HAVE FINISHED
THE PTOA PV PRESSURE FOCUS STUDY AREA

Your Mentor gives all Brilliant PTOA Readers and Students ...

meaning those who have been reading the PTOA Segments in the intended, sequential order...

a hearty round of applause for finishing the PTOA PV Pressure Focus Study Area! Quite an acheivement!

This milestone will be celebrated by checking off the remaining PTOA PV Pressure Focus Studies that have been completed since PTOA Segment #203.

Since that PTOA Segment, PTOA Readers and Students have finished Parts 6, 7 and 8 on the PTOA PV Pressure Focus Study Area Outline.

Remember how the process works, Fred?

The PTOA PV Pressure Focus Study Area Outline is listed below.

A check mark in a block denotes content which has been featured and the corresponding PTOA Segment link will be in parentheses.

Fred, are you ready to check off all the remaining important PV Pressure concepts you have learned?

Let's DO THIS!

 

 

CHECKLIST CHECKOFF: THE PTOA PV PRESSURE FOCUS STUDY AREA 
PART 1: THE INTRODUCTION TO PV PRESSURE FUNDAMENTALS

  • Pressure is simply a Force (F) applied over a Surface Area (A).

    ☑Industrial Applications of the PV Pressure. (PTOA Segment #140).

  • ☑P is For Pressure! - the ISA Symbols for PV Pressure. (PTOA Segment #141)
  • ☑The Definitions of Pressure: P = Force/Area and Gravitational Force F=(Mass) X (Acceleration of Gravity). (PTOA Segment #142)
  • ☑The Difference between a Pound of Mass and a Pound of Force. (PTOA Segment #143)
  • ☑The Overlooked Assumptions that Allow Equating a  a Pound of Force to a Pound of Mass. (PTOA Segment #144).
  • ☑How to Calculate the Hydrostatic Pressure of Any Liquid in a Container. (PTOA Segment #145)
  • ☑Dams, Tanks, and Vessels are Examples of (Hydraulic) Head Pressure. (PTOA Segments #146 and #147)
  • ☑Common Conversion Factors Used in Process Industry for SI and English Units. (PTOA Segment #148)
  • ☑The Differences Between Absolute, Atmospheric, Gauge, and Vacuum Pressures and their respective industrial applications. (PTOA Segments #149, #150)
  • ☑

    A "Vacuum Pressure" is less than Atmospheric Pressure (14.7 psia=1 ATM).

    Vacuum Pressures, Creating Vacuum Pressures, Industrial Uses of Vacuum Pressures. (PTOA Segment #151)

  • ☑Predictable Gas and Liquid Behavior Called "Laws." (PTOA Segments #152, #153, and #154).

PART 2: THE INTERRELATIONSHIP OF THE PV PRESSURE WITH PV TEMPERATURE, PV FLOWRATE, AND PV LEVEL 

 

☑The PV Pressure/PV Temperature Relationship: (PTOA Segment #157)

    • ☑PV Pressure Impact on Boiling Point Temperature, Freeze Point Temperature, Condensation Temperature.
    • ☑Local Atmospheric Pressure and Boiling Point Temperature.
    • ☑Process Industry Examples that Use the PV Pressure/PV Temperature Relationship.

 

 

☑The PV Pressure and PV Flowrate Relationship: (PTOA Segment #158).

    • In any flowing fluid, when the Fluid Velocity increases, the sensed Pressure in the line Decreases ... and vice versa! Pressure and Fluid Velocity Swap!

      ☑The PV Pressure ↔ Fluid Velocity Swap, (PTOA Segment #159)

    • ☑"The Power of the Swap" makes it possible to infuse the PV Pressure into a flowing liquid!
    • ☑Delta P (aka ΔP, dp, Pressure Drop, Pressure Gradient) ... No Delta P=No Flow.
    • ☑Process Industry Examples that Use the PV Pressure/PV Flowrate Relationship.

 

 

  • The greater the level of liquid, the greater the hydrostatic Pressure sensed at the bottom of the tank!

    ☑The PV Pressure/PV Level Relationship: (PTOA Segment #160)

    • ☑The Hydrostatic Head (and potential Pressure Energy) of Stored Liquids.
    • ☑The PV Pressure/PV Level Relationship and Liquid/Vapor Equilibrium.
    • ☑Process Industry Examples that Use the PV Pressure/PV Level Relationship.

 

 

 

 

 

  • ☑The Relationship Between Rotating Equipment and Process Operators. (PTOA Segment #161)

 

  • ☑Review of the Physical Properties of Fluids (Density, Specific Gravity, Etc.). (PTOA Segment #162)

:

CONSIDER THE PTOA PV PRESSURE FOCUS STUDY AREA CONTENT TO BE CHECKED-OFF!

 

ONWARD!

 

 

TAKE HOME MESSAGES: PTOA Readers and Students should be proud of themselves for completing the PTOA PV Pressure Focus Study Area.  Understanding what the PV Pressure is and how Rotating Equipment infuses liquids and gases with Pressure Energy is much more difficult than understanding the PV Temperature. 

Next Up? PTOA Readers and Students will begin the PTOA PV Flowrate Focus Study Area.
