Flow is a measure of air output in terms of volume per unit of time. The common units are litres per minute, cubic feet per minute (CFM), etc. Velocity refers to how fast the air is moving in distance per unit of time.

Speed is a measure of distance traveled over a certain amount of time, while velocity measures displacement over time, as opposed to distance. ... The rate of change for velocity is acceleration, which is measured in displacement over time over time (e.g., m / s^2).

The law states that the flow rate is equal to the pressure drop along the tube divided by the resistance to flow. This resistance in turn is directly proportional to the viscosity. Thus the flow rate is inversely proportional to the viscosity.

Flow is a measure of air output in terms of volume per unit of time. ... Velocity refers to how fast the air is moving in distance per unit of time. The common units are feet per second, metres per second, etc. ​Pressure is the measure of force applied on an area.

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware.

The short answer is that velocity is the speed with a direction, while speed does not have a direction. Speed is a scalar quantity—it is the magnitude of the velocity. Speed is measured in units of distance divided by time (e.g., miles per hour, feet per second, meters per second, etc.).

The average speed is the distance (a scalar quantity) per time ratio. ... On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

In physics and engineering, mass flow rate is the mass of a substance which passes per unit of time. Its unit is kilogram per second in SI units, and slug per second or pound per second in US customary units. The common symbol is. (ṁ, pronounced "m-dot"), although sometimes μ (Greek lowercase mu) is used.

In simpler words, density = number of molecules x molecular weight/volume occupied, while the viscosity is a measurement of the inter-molecular forces and molecule shapes. Viscosity tells you the “friction” between two layers of the given fluid, while density varies slightly with temperature, viscosity changes rapidly.

Velocity is vector quantity but speed is scaler quantity. THE BASIC DIFFERENCE BETWEEN SPEED AND VELOCITY IS: ... SPEED HAS ONLY MAGNITUDE AND NO DIRECTION WHEREAS VELOCITY HAS BOTH MAGNITUDE AND DIRECTION. 2. SPEED IS ALWAYS POSITIVE(THAT IS NON - NEGATIVE AND NON-ZERO) WHEREAS VELOCITY IS EXACTLY THE OPPOSITE.

Technically,they are same thing from fluid mechanics point of view. It is volume or mass rate of flow of liquid. However,discharge is specifically used when liquid is flown out of some constrained portion like from a pipe to open atmosphere. The flow rate at the exit of pipe is called discharge.

Pressure drop is comparative to volumetric flow rate under laminar flow conditions. When the flow rate is double, there is double the pressure drop. Pressure drop decreases when common mode pressure increases. Pressure drop increases as the square of the volumetric flow rate under turbulent flow conditions.

What is the difference between velocity, density, and viscosity? ... The velocity of the fluid movement or plate for example / height of the film is the shear rate. Shear stress/Shear rate= viscosity (dynamic).

Standard flow rate is a correction applied to an actual flow measurement based on a given temperature and pressure. ... Actual flow rate is the actual volume of fluid that passes a given point based on given pressure and temperature of the process.

As nouns the difference between flow and fluid is that flow is the movement of a fluid while fluid is (physics) any substance which can flow with relative ease, tends to assume the shape of its container, and obeys bernoulli's principle; a liquid, gas or plasma.
