Flow rate is volume of liqid flowing per unit time, velocity is displacement per unit time. For a constant cross-section area, the flow rate would increase with velocity and vice versa. This is because the volume flowing per unit time obviously increases if distance covered by the fluid increases.
Picture a fluid flowing through a cylindrical pipe.

How is flow rate related to pressure?
Flow rate is directly related to pressure in a system. As pressure increases, flow rate typically increases as well. This relationship can be described by principles such as Bernoulli's equation, which shows that an increase in pressure leads to an increase in fluid velocity and thus flow rate.
What is the definition of velocity gradient?
With respect to material being sheared, velocity gradient is the change dv in relative velocity v between parallel planes with respect to the change dr in perpendicular distance r throughout the depth of the material. Velocity gradient has the same dimensions as rate of shear, which is reciprocal seconds.
Calculate water flow?
To calculate water flow rate, you need to know the cross-sectional area of the pipe or channel through which the water is flowing, as well as the velocity of the water. The formula for calculating water flow rate is Q = A * V, where Q is the flow rate, A is the cross-sectional area, and V is the velocity of the water. Multiplying the area by the velocity will give you the flow rate.
How do you calculate air flow rate through a tapered cylinder?
Using conservation of mass: mass flow rate = ρ * V * A where ρ= density, V= velocity, and A= cross sectional area therefore since massin = massout therefore: (ρ*V*A)in = (ρ*V*A)out
What is the definition of velocity time graph?
A velocity-time graph shows how an object's velocity changes over time. The slope of the graph represents the object's acceleration, and the area under the curve represents the total displacement of the object. It is a useful tool for understanding an object's motion.
What is the relationship between flow rate pressure?
With the increase in flow rate the velocity of the fluid increases. and with the increase in velocity the pressure decreases, because there will be pressure drop (Refer Bernoulli's Theorm). So with increase in Flow rate the pressure decreases.
What is the relationship between velocity gradient and fluid flow in a dynamic system?
The velocity gradient in a fluid flow system refers to the change in velocity across different points in the fluid. In a dynamic system, the velocity gradient is directly related to the fluid flow rate. A higher velocity gradient indicates a faster flow rate, while a lower velocity gradient indicates a slower flow rate. This relationship helps to understand how the fluid moves and behaves within the system.
What is the relation between velocity and acceretion?
Acceleration is the rate of change of velocity with respect to time. If an object's velocity is increasing, it is accelerating positively. If its velocity is decreasing, it is accelerating negatively.
How do you calculate flow velocity in a fluid system?
Flow velocity in a fluid system can be calculated by dividing the flow rate of the fluid by the cross-sectional area of the pipe or channel through which the fluid is flowing. The formula for calculating flow velocity is: Velocity Flow Rate / Cross-sectional Area.
How can one determine the flow velocity in a fluid system?
One can determine the flow velocity in a fluid system by measuring the rate of flow and the cross-sectional area of the system. By dividing the flow rate by the cross-sectional area, the flow velocity can be calculated.
How can you calculate water velocity from flow rate or diameter of pipe?
if u r talking about presuure drop then it can be easily calculate with the help of relation 4flv*v/2gd in that f is the friction factor which is different for vraious type of flow for that u have to search a good book of fluid mechanics, v is the velocity. length of pipe and d is diameter of pipe
How can one determine velocity from flow rate?
To determine velocity from flow rate, you can use the formula: Velocity Flow Rate / Cross-sectional Area. This formula calculates the speed at which a fluid is moving through a given area based on the flow rate of the fluid and the cross-sectional area of the pipe or channel through which it is flowing.
How do you calculate the velocity of a pipe flow?
To calculate the velocity of a pipe flow, you can use the formula: Velocity Flow rate / Cross-sectional area of the pipe. The flow rate is typically measured in cubic meters per second, and the cross-sectional area is the area of the pipe's opening in square meters. By dividing the flow rate by the cross-sectional area, you can determine the velocity of the flow in meters per second.
How do you calculate air velocity in a pipe?
To calculate air velocity in a pipe, you would need to measure either the volumetric flow rate or the mass flow rate of air flowing through the pipe. You can then use the formula: air velocity = volumetric flow rate / cross-sectional area of the pipe, or air velocity = mass flow rate / (density of air * cross-sectional area of the pipe).
How to calculate flow velocity in a pipe?
To calculate flow velocity in a pipe, you can use the formula: velocity flow rate / cross-sectional area of the pipe. The flow rate is typically measured in volume per unit time (e.g. cubic meters per second), and the cross-sectional area is the area of the pipe's opening. By dividing the flow rate by the cross-sectional area, you can determine the velocity of the flow within the pipe.
What is difference between flow rate and flow velocity in flow tubes?
Flow rate is the volume of fluid passing through a section of the tube per unit time, usually measured in volume per unit time (e.g. cubic meters per second). Flow velocity is the speed at which the fluid is moving through the tube, usually measured in distance per unit time (e.g. meters per second). While flow rate depends on the cross-sectional area of the tube, flow velocity is independent of the tube's size.
How to calculate flow rate in a pipe system?
To calculate flow rate in a pipe system, you can use the formula Q A V, where Q is the flow rate, A is the cross-sectional area of the pipe, and V is the velocity of the fluid. You can measure the area of the pipe and the velocity of the fluid to determine the flow rate.
