Q:

Why is pyroclastic flow dangerous?

A:

The danger of pyroclastic flow comes from its speed and heat. According to Michigan Technological University, pyroclastic flows have reached extreme high temperatures, including flows from the Mt. Pelee eruption that got as hot as 1,967 Fahrenheit (1,075 Celsius).

Pyroclastic flow is an extremely dangerous form of lava flow resulting from volcanic eruption. It moves very fast thanks to its consistency and the effects of gravity. These flows are highly destructive and can quickly burn any vegetation, structures, and animals — including humans — that are in their paths. Because it moves so quickly, evacuating from a pyroclastic flow can be difficult if volcanic eruptions occur without warning.

  • Q:

    What is a pyroclastic flow?

    A:

    Pyroclastic flows are enormous ejections of debris from erupting volcanoes. They consist of large rocks and smaller particles of ash and dust that travel across the surrounding landscape at tremendous velocity.

  • Q:

    How fast does a pyroclastic flow travel?

    A:

    Pyroclastic flows travel away from a volcano's vent at speeds up to 150 kilometers per hour. They contain hot gas, ash and rock at temperatures ranging from 100 to 800 degrees Celsius.

  • Q:

    How do you measure the water flow through a pipe?

    A:

    The water flow though a pipe is measured by using a mechanical flow meter. These work through positive displacement, where the volume of water flowing though in a given amount of time is measured. Domestic areas typically use a piston/rotary positive displacement meters or a nutating disk meter, while commercial areas use turbine flow meters.

  • Q:

    What is the difference between laminar and turbulent flow?

    A:

    Laminar and turbulent flows are the two major forms of fluid flow, with laminar flow being an orderly flow with all the fluid molecules moving parallel in the direction of flow, whereas in turbulent flow, different streams of fluid form eddies and unpredictable currents in a different direction than the overall direction of flow. Which type of flow arises in a fluid depends on its speed relative to its viscosity and the size and shape of the pipe or other channel carrying the fluid. Viscosity is the resistance to flow, and more inherently viscous fluids are more resistant to turbulence.
