Session 15: Review exercise #2 (2 hours)

Time: 2 hours

Objectives: By the end of this session trainees will have demonstrated their ability to:

· determine maximum drive and delivery heads for a given ram;

· describe key interrelationships in a hydram;

· accurately describe at least 5 factors affecting efficiency in a hypothetical ram installation.

Overview: Work to date in the three areas described above has been primarily group work. This activity provides the opportunity to apply this information individually, and clarify any misunderstandings.

Materials: Handout 15A

TRAINERS NOTE:

Specifications for problem #1 need to be provided, using the charts from Sessions 9 and 10. Alternatively, participants can take actual measurements from the pipefitting rams they constructed, and solve the problem for those rams.

Procedures
