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


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.



1. Explain purpose of-session, resolve any hanging questions from previous session.


2. Distribute handout, instructing participants to solve problems individually.

Allow 30 minutes for this.

3. Participants to compare answers in groups of 24, coming to agreed upon solution(s).

30 min.

4. For each problem, ask for volunteers and provide group answers. Check with other groups for variation/difference. Discuss rationale for answers, and/or differences.
