Flow rate and velocity
Thread Content
How are flow rate and velocity expressed in English? I have always used flowrate to refer to two things! ! Please give your advice
Flow rate: Flow is sufficient; speed of flow: flow velocity/rate
Flow rate: flowrate; Velocity: Speed
Flow rate: velocity of flow; speed of velocity. In some articles, velocity is used directly. Flow capacity: amount of flow that can pass through
But in many foreign articles I’ve seen the term used is flowrate,!!!! with the unit being kmol/h; so it should refer to the flow rate. Last edited by niulijun117 on 2009-2-25 10:43.]
Oh, thank you. I wanted to give a rating, but I’ve already finished doing that today! Regret
kmol/h is the flow rate, specifically the molar flow rate. Flow rate is generally referred to as flow rate, such as volumetric flow rate, mass flow rate, or molar flow rate. Velocity, on the other hand, refers to the speed of flow. Last edited by niuky on 2009-2-25 11:05.]
Velocity refers to the linear speed; length/time. Flowrate refers to the volume flow rate; mass, volume, moles/time
According to Jishu King, as the original poster mentioned, both of these terms can be expressed as \"flowrate\"; in English, different units are used to denote different meanings, while \"velocity\" refers only to speed
Flow rate: velocity of flow; speed of velocity. Flow capacity: This term is derived from the \"Chinese-English Dictionary of Petrochemicals\"
Flow rate, the amount of fluid that passes through in a unit of time (flow rate). Ø Volume flow rate, V, [m3/s], determined by T and P. Ø Mass flow rate, W, [kg/s]. Ø Mole flow rate, [mol/s]. Flow velocity, the distance that the fluid travels in a unit of time (velocity), [m/s]. Ø Average velocity, the volume of fluid that passes through a unit cross-sectional area in a unit of time.
