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.

Velocity is the speed at which a fluid moves past a specific point, while flow rate is the volume of fluid that passes through that point per unit time. The flow rate is directly related to velocity through the equation Q = A * V, where Q is the flow rate, A is the cross-sectional area of the flow, and V is the velocity of the fluid.

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?
Velocity gradient is the rate of change of velocity with respect to distance in a fluid flow. It represents how velocity changes across different points in a fluid, indicating the level of shear and deformation within the fluid. Typically, it is used to describe the flow behavior or viscosity of a fluid.
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?
To calculate the air flow rate through a tapered cylinder, you need to use the continuity equation, which states that mass flow rate is constant in a fluid system. You would need to know the cross-sectional area of the cylinder at different points along its length, as well as the velocity of the air flow. By integrating the velocity over the cross-sectional area of the cylinder, you can determine the air flow rate.
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 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 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 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
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 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).
Differentiate between steady flow and pipe unsteady flow?
Steady flow refers to a condition where the flow rate in a system does not change with time. Pipe unsteady flow, on the other hand, involves variations in flow rate over time due to changes in conditions such as pressure or velocity within the pipe. Steady flow is typically easier to analyze and predict, while unsteady flow requires more complex modeling.
Relation between angular velocity and linear velocity?
Angular velocity is the rate of change of an object's angular position with respect to time, while linear velocity is the rate of change of an object's linear position with respect to time. The relationship between angular velocity and linear velocity depends on the distance of the object from the axis of rotation. For an object rotating around a fixed axis, the linear velocity is equal to the angular velocity multiplied by the radius of the rotation.
What is relation between mass flow rate and discharge pressure in reciprocating compressor?
The mass flow rate and discharge pressure in a reciprocating compressor are directly related. As the discharge pressure increases, it can result in a higher mass flow rate through the compressor. This relationship is important for determining the performance and efficiency of the compressor in various operating conditions.
How might speed at which a gas particle moves affects how quickly that gas particle escapes from the balloon?
Flow rate is diameter of hole*velocity, so the higher the velocity the higher the flow rate.
What is relation between flow rate and actuator speed?
Flow rate is directly proportional to actuator speed. Increasing the actuator speed will result in higher flow rates, while decreasing actuator speed will decrease flow rates. Actuator speed controls the flow of a fluid or material through a system by adjusting the rate at which the actuator allows the material to flow.
What are limitations of velocity of flow in a pipeline?
The velocity of flow in any pipe is determined by three things. The internal pipe diameter, the mass flow rate of the liquid and the fluid density.
