pump head pressure basics

The video tutorial explains the concept of head pressure in pumps, highlighting its measurement in feet or meters due to the varying properties of different liquids. It discusses the importance of head pressure in ensuring pumps can move liquids to higher elevations, overcoming friction and pressure losses. The tutorial also covers pump charts, illustrating the relationship between head pressure and flow rate, and explains how flow rate is measured in various units.

Why do pump manufacturers measure head in feet or meters instead of PSI or bar?

• Because it is a standard practice in the industry.

• Because PSI and bar are not suitable for liquids.

• Because feet and meters are more accurate units.

• Because they only know how high their pump can push a liquid.

What happens if a pump cannot overcome the friction and pressure losses in a system?

• The pump will increase its flow rate.

• The liquid will not reach the desired elevation.

• The system will automatically adjust the pressure.

• The pump will operate more efficiently.

In a commercial heating system with long pipes, what type of pump is needed?

• A pump with adjustable speed.

• A pump with high head pressure.

• A pump with high flow rate.

• A pump with low head pressure.

What does the vertical Y axis represent on a pump chart?

• Liquid type

• Pump efficiency

• Flow rate

• Head pressure

What is the effect of rotating a pump from horizontal to vertical on flow rate and pressure?

• Flow rate increases, pressure decreases.

• Both flow rate and pressure increase.

• Flow rate decreases, pressure increases.

• Both flow rate and pressure decrease.
