How do you measure viscosity?

A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used.

What is viscosity GCSE?

viscosity (a measure of how they flow)

What other methods are used to determine the density of liquid?

Common laboratory gravimetric procedures for determining density are the buoyancy technique, the displacement principle and the pycnometer method.

How do you find the density of a liquid GCSE?

The most accurate way to calculate the density of any solid, liquid or gas is to divide its mass in kilograms by its volume (length × width × height) in cubic metres. The unit for density is kg/m 3. The density of water is approximately 1000 kg/m 3 and the density of air is approximately 1.2 kg/m 3.

What is the instrument used to measure viscosity?

Viscometer
Viscometer, instrument for measuring the viscosity (resistance to internal flow) of a fluid.

What are the two methods of cracking?

Cracking is primarily of two types – thermal cracking and catalytic cracking. Thermal cracking is further categorised into modern thermal cracking and steam cracking. On the other hand, sub-classifications of catalytic methods of cracking are hydrocracking and fluid catalytic cracking. 3.

What instrument do you use to measure density?

Hydrometer
Hydrometer, device for measuring some characteristics of a liquid, such as its density (weight per unit volume) or specific gravity (weight per unit volume compared with water).

How to make viscosity of liquids science experiment?

Step 1 – Gather four clear glass jars and fill one with water, one with corn syrup, one with cooking oil (we used vegetable oil, but any cooking oil will work) and one with honey. As you are pouring the liquids, take a moment to make observations. What do you notice as you pour the water into the glass?

What do you need to know about viscosity in engineering?

They experience what viscosity means, and also practice using algebra and unit conversions. This engineering curriculum aligns to Next Generation Science Standards ( NGSS ). Through fluids of different viscosities, balls fall at different speeds. Left to right: Dial soap, SW 30 oil and 10W30 motor oil.

How is the viscosity of a fluid determined?

Determination of Viscosity Viscosity of fluids can be determined using a viscometer. The viscometer we will use in this lab will measure dynamic viscosity which is the internal resistance of a fluid to flow when an external force is acting upon the fluid. The external force in this case would be the mixer in the viscometer.

Why is viscosity so important in food science?

Viscosity is an important parameter that relates to texture and appearance of food and hence sensory experience while eating. Viscosity is also important in the rate of fluid flow and the amount of energy that may be required to move liquids in pipes. As it relates to fluid flow, there are generally two types.
