Net Positive Suction Head (NPSH) Definition & Calculation / 1.0 Hour / August 14, 2025 / Webinar

Net Positive Suction Head (NPSH) Definition and Calculation

 Date: Thursday, August 14, 2025 

Time: 1:00 PM - 2:00 PM 

  PDH Credits: 1.0 

Overview:

This training provides detailed definition and instruction on how Net Positive Suction Head Available (NPSHA) is calculated. Various system calculation examples for NPSHA are worked through, which explain any nuance you may need to understand, including, calculations based on pressure measurements, tank levels, and system frictional losses are detailed. Tutorials are provided on pressure, converting gauge pressure to gauge head, Bernoulli’s and the continuity equation, when velocity head needs to be considered, how to correct atmospheric pressure based on altitude and how to calculate friction head loss. Attendees learning is reinforced from multiple presented examples. 

Learning Level – Intermediate:

Intermediate level training is designed for individuals who have some experience and basic knowledge on the topic. 

It builds upon basic concepts and expands the breadth and depth of understanding supporting the development of skills.  

Audience:

Individuals looking gain in depth technical knowledge or those looking for a refresher, including pump system designers, engineers, technical support, test technicians and engineers, reliability and rotating equipment engineer, and experienced maintenance and operation personnel. 

Learning Objective:

• How to define NPSHA and evaluate it for different system configurations 
• What is cavitation and why it occurs 
• Understand and apply Bernoulli’s equation 
• Understand gauge, absolute, vacuum, atmospheric and vapor pressures 
• Convert pressure to head for various fluid properties 
• How to calculate frictional head loss 
• How to correct atmospheric pressure based on elevation 
• Calculate NPSHA based on gauge pressure measurements, fluid levels, frictional head loss, atmospheric pressure, and velocity head 
• Few brief points/bullets that explain what knowledge the participants will gain knowledge upon completion of the webinar. (NORMAL Text FONT)

Licensed Professional Engineers

Continuing professional development is a vital component of the engineering licensure process. Most state licensing boards require continuing professional development as a condition for licensure and renewal of the license to practice engineering. The acceptance of continuing education as it applies to fulfillment of the state licensing requirements for professional designations is at the pleasure of the individual state licensing boards. It is the responsibility of the individual participants to be knowledgeable about their state requirements. Pre-approval of training providers and courses is not required by most state licensing boards, except for the following:

Florida Board of Professional Engineers

Pump Systems Matter is a board-approved continuing education provider for the Florida Board of Professional Engineers: License # CEA361.

New York State Board for Engineering, Land Surveying, and Geology

Pump Systems Matter is approved as a sponsor of continuing education for professional engineers in New York State: NYS Sponsor # 241.
