Question
![*For questions a) and b), you must answer directly on the graph on the next page when required
to do so (figure 2.2)*
You must pump 5°C water from a large open-air reservoir to another at a rhythm of 1 1/s. The pipe
linking both reservoirs is one inch in diameter, has a Hazen-Williams coefficient of 140 and measures 1
km (975 m of which are found after the pump displayed on figure 2.1).
Singular head loss can be neglected.
Based on figures 2.1 and 2.2, you must:
a) Select the most adequate pump to complete your project:
b) Identify the point of operation (minimum 3 points must be calculated on the pipe characteristic
curve);
c) Determine if cavitation could be an issue.
N.B. presume atmospheric pressure to be 101.3 kPa.
