Mass flow rate is the measure of how much mass is flowing through a given point in a given period of time. It is usually represented in units of kg/s.
The mass flow rate can be affected by many factors such as the density of the fluid the velocity of the fluid and the area of the pipe or channel through which the fluid is flowing.
In order to calculate the mass flow rate the following equation can be used:
m = ρ * v * A
where m is the mass flow rate in kg/s ρ is the density of the fluid in kg/m3 v is the velocity of the fluid in m/s and A is the area of the pipe or channel in m2.
For example if a fluid with a density of 1000 kg/m3 is flowing through a pipe with a cross-sectional area of 0.1 m2 at a velocity of 2 m/s the mass flow rate would be:
m = 1000 kg/m3 * 2 m/s * 0.1 m2 = 20 kg/s
The mass flow rate is an important parameter in many industries such as the food and beverage industry the chemical industry and the oil and gas industry. It is used to calculate the amount of material that needs to be transported the amount of heat that needs to be transferred and the amount of power that needs to be generated.
There are many different types of flow meters that can be used to measure the mass flow rate of a fluid. The most common type of flow meter is the orifice meter which is used to measure the flow rate of liquids. Other types of flow meters include the rotameter the positive displacement meter and the Coriolis meter.
The orifice meter works by measuring the differential pressure across an orifice plate. The orifice plate has a small hole in it and as the fluid flows through the hole the pressure of the fluid decreases. The pressure difference is then used to calculate the flow rate.
The rotameter is a type of flow meter that uses the principle of conservation of angular momentum to measure the flow rate. The meter consists of a tube that is partially filled with a liquid. The level of the liquid in the tube is used to calculate the flow rate.
The positive displacement meter is a type of flow meter that uses the displacement of a piston or a rotor to measure the flow rate. The meter consists of a chamber that is filled with the fluid. The piston or rotor is then used to displaced a certain volume of the fluid and the flow rate is calculated based on the displacement.
The Coriolis meter is a type of flow meter that uses the Coriolis effect to measure the flow rate. The meter consists of a chamber that is filled with the fluid. The fluid is then subjected to a rotating force and the flow rate is calculated based on the amount of force required to maintain the fluid in the chamber.
Mass flow rate is an important parameter in many industries and there are many different types of flow meters that can be used to measure it.
What is mass flow rate?
