Use the term “viscosity” to explain how wetting agents are used to help fight fires. A liquid with a high viscosity has particles that like to stick together instead of spread out. … The wetting agent allows the water to spread out more easily instead of sticking together.

## How can viscosity help fight fires?

**When a liquid has less viscosity, it flows faster**. Therefore, this is how viscosity is used in wetting agents to fight fire.

## What is viscosity flow?

Viscosity is **defined as the resistance to flow**!

Viscosity of often referred to as the thickness of a fluid. You can think of water (low viscosity) and honey (high viscosity). … Just like in the case of friction between moving solids, viscosity will determine the energy required to make a fluid flow.

## How flow rate is affected by viscosity cohesion and adhesion?

Two factors are cohesion and adhesion. Cohesion is the force of attraction between the particles of a substance. Fluids with slow flow rates, such as maple syrup, have particles with greater cohesion. … Thicker fluids are more **viscous** and have slower flow rates.

## Does temperature affect viscosity?

The liquid viscosity is highly affected by the heat. The **viscosity decreases with an increase in temperature**.

## What factors affect viscosity?

The two main factors that affect viscosity are **temperature and silica content**.

## Does higher viscosity mean slower flow rate?

Viscosity is the measure of resistance of a fluid to flow. A fluid that is highly viscous has a high resistance (like having more friction) and **flows slower than a low-viscosity** fluid. To think of viscosity in everyday terms, the easier a fluid moves, the lower the viscosity.

## What happens when viscosity increases?

Viscosity is a measure of an oil’s resistance to flow. It decreases (thins) with increasing temperature and increases (or thickens) **with decreased temperature**. … A general increase in viscosity at higher temperatures, which results in lower oil consumption and less wear.

## How does heat affect viscosity and flow rate?

Viscosity and Temperature

When a liquid heats up, **its molecules become excited and begin to move**. The energy of this movement is enough to overcome the forces that bind the molecules together, allowing the liquid to become more fluid and decreasing its viscosity.

## How do you find the flow rate of viscosity?

There are several formulas and equations to calculate viscosity, the most common of which is **Viscosity = (2 x (ball density – liquid density) x g x a^2) ÷ (9 x v)**, where g = acceleration due to gravity = 9.8 m/s^2, a = radius of ball bearing, and v = velocity of ball bearing through liquid.

## What is force of viscosity?

1. n. [Enhanced Oil Recovery] **A measure of a fluid’s resistance to flow**. Viscous forces in a fluid are proportional to the rate at which the fluid velocity is changing in space; the proportionality constant is the viscosity.

## What are some examples of viscosity?

This corresponds to the informal concept of “thickness” — for example, **honey** is thicker and has a much higher viscosity than water.

…
