Detailed Analysis

CourseMarks Score®

9.0 / 10

CourseMarks Score® helps students to find the best classes. We aggregate 18 factors, including freshness, student feedback and content diversity.

Freshness Score

9.9 / 10
This course was last updated on 3/2021.

Course content can become outdated quite quickly. After analysing 71,530 courses, we found that the highest rated courses are updated every year. If a course has not been updated for more than 2 years, you should carefully evaluate the course before enrolling.

Student Feedback

We analyzed factors such as the rating (0.0/5) and the ratio between the number of reviews and the number of students, which is a great signal of student commitment.

New courses are hard to evaluate because there are no or just a few student ratings, but Student Feedback Score helps you find great courses even with fewer reviews.

Content Score

7.6 / 10
Video Score: 7.9 / 10
The course includes 2h 26m video content. Courses with more videos usually have a higher average rating. We have found that the sweet spot is 16 hours of video, which is long enough to teach a topic comprehensively, but not overwhelming. Courses over 16 hours of video gets the maximum score.

Description

This is a rigorous course on Net Positive Suction Head, cavitation and recirculation. The course material has been compiled based on information from several handbooks, manufacturers recommendations, industry best-practice, guidelines given in norms and standards and contents of research papers and conference presentations. All the above has been blended in the light of the authors field experience.
The course focuses on the concepts and practical implications related to
•NPSHi, NPSH3, NPSHR (required) and NPSHA (available)
•Cavitation
•Recirculation
on pumping system’s life and performance. And to learn how to
•Measure NPSH – NPSH testing, permissible tolerances
•Provide adequate NPSH margin as per industry guidelines
•Improve the NPSHA and reduce NPSHR
•Mitigate the adverse effects of cavitation, recirculation
The course comprises of 13 lecture and 6 exercises covering the topic in detail. It covers the following:
•Definition and calculation of specific speed and the corresponding shapes of the pump characteristic curves,
•Definition and calculation of suction specific speed and its impact on cavitation and recirculation,
•Detailed explanation of NPSH, cavitation and recirculation phenomenon,
•Suction Specific speed and reliability,
•NPSH margin and NPSH margin ratio to avoid cavitation and recirculation,
•NPSH testing of pumps,
•Methods to improve the NPSH available,
•Methods to decrease the NPSH required,
•How to detect cavitation in the field,
•Identify the operational problems through examination of the damage pattern to the pump parts,
•How to prevent or minimize the cavitation and recirculation damage in the field.

Requirements

• Must be familiar with the basics of rotodynamic pumps
• Engineering knowledge and field experience is desirable
• Knowledge related to rotary machines and overall maintenance is helpful

You will learn

✓ Meaning of NPSH3, NPSHR and NPSHA in practical terms
✓ Relationship between NPSHR, cavitation and recirculation
✓ Factors which lead to cavitation and recirculation in pumps and pumping systems
