The units of mass flow include kg s, kg h, t h.
The unit of mass flow is usually expressed in kilograms per second (kg s). If you need to convert to other units, you can also use grams per second (g s) or other different combinations. For example, milligrams per second (mg s) is a unit 1,000 times smaller than grams per second (g s), while tons per hour (t h) are 3,600 times larger than kilograms per second (kg s).
In physics, mass flow refers to the mass that passes through an area per unit of time in a fluid or gas. In fluid mechanics and aerodynamics, mass flow is often used to describe the physical properties of fluids or gases, and is an important parameter for studying fluid or gas dynamics equations.
Because the magnitude of the mass flow rate is related to parameters such as viscosity, density, velocity, area, etc., the calculation method will also be different. In practice, mass flow is often affected by external factors such as temperature, pressure, and density. The mass flow rate will also vary under different conditions.
External Factors Affecting Mass Flow:
1. Temperature and pressure: Temperature and pressure are important parameters that affect the mass flow rate, and have an impact on various properties such as the density dissipation, volume and velocity of fluids and gases.
2. Density: Density is an important factor affecting mass flow. All other parameters being constant, the higher the density, the greater the mass flow.
3. Viscosity: Viscosity is the internal friction of the fluid, the larger the mass flow of the fluid.
4. The velocity and direction of the fluid or gas: The velocity and direction of the fluid bridge or gas will also affect the mass flow. When the flow rate increases, so does the mass flow rate; Depending on the direction of flow, the mass flow rate will also vary.
5. Flow rate and area of fluid: In the same time, both the flow rate of the fluid and the area occupied by the fluid will affect the mass flow.
6. The degree of mixing of fluid or gas: the degree of mixing of fluid or gas will have an impact on the mass flow, the stronger the fluid mixing, the greater the mass flow.

Mass flow refers to the mass of fluid per unit of time through the effective section of a closed pipe or open slot. Units: kg h, kg s. Corresponding to the volumetric flow rate (the volume of fluid passing through per unit time), it can be expressed as the product of the volumetric flow rate and the density of the fluid.
Mass flow velocity is defined as the mass of the fluid flowing through the unit flow cross-sectional area per unit of time, that is, the mass flow rate borne by the unit flow-through cross-sectional area, usually expressed in g and in kg (m2*s).
Calculation of mass flow velocity: g = w a, where w is the mass flow rate in kg s; A is the circulating area, and the unit is m2.

Mass flow: The mass of the fluid passing through any section of the pipeline per unit time is called the mass flow rate. Mass Flow Velocity: The mass of fluid flowing through a unit section of a pipe per unit of time is called mass flow velocity.

Volume Flow Mass Flow The density of the material in that state.
The so-called standard volumetric flow rate is of little significance to liquids because they are basically incompressible fluids.
For gases, it can be approximated as an ideal gas, and according to Charles's law p1v1 t1 p2v2 t2, the volume flow rate in the standard state can be approximated.

The mass flow meter is a thermally sensitive measurement, and the flow rate is measured by the molecular mass taken away by the split molecules, because it is a thermally sensitive measurement, so it will not affect the measurement results due to changes in gas temperature and pressure. Mass flow meter is a more accurate, fast, reliable, efficient, stable and flexible flow measurement instrument, which will be more widely used in petroleum processing, chemical industry and other fields, and is believed to show great potential in promoting flow measurement. The mass flow meter cannot control the flow rate, it can only detect the mass flow of liquids or gases, and output the flow value through analog voltage, current or serial communication. >>>More
