Technically speaking most people consider time like a river, you just flow down, and you can travel "upstream" but it takes a lot of energy. But in reality time moves in strange ways not even fully understood by the leading scientists thought it is believed by some that it folds on to itself, and is like one big loop. one thing could be happening here and the same thing thousands of millennia in the future could be happening.

What is the definition of steady and unsteady flow of fluid?
Steady flow of fluid is when the flow parameters (velocity, pressure, density) at a point do not change with time. Unsteady flow is when these parameters vary with time at a particular point.
What is transient flow?
A flow lasting only a short time
What is an unsteady flow?
An unsteady flow refers to a fluid flow where the properties at a specific point in the flow field change with time. This could be due to variations in velocity, pressure, or density over time. It contrasts with steady flow, where these properties remain constant at any given point in the flow field over time.
How do you find flow rate given volume and time?
The flow rate is simply the volume moved in a specific time; divide the volume by the time.
What is the difference between steady flow and unsteady flow?
Steady flow refers to fluid flow where the conditions (velocity, pressure, temperature) at any given point do not change with time, while unsteady flow involves conditions that vary with time, such as in transient flow situations where these conditions change over time. Steady flow conditions are easier to analyze mathematically, while unsteady flow conditions are more complex and require time-dependent equations to describe the behavior of the system.
Stock and flow concept in macroeconomics?
Stock concept doesn't have a time reference whereas Flow concept has time reference i.e. Stock concept gives the value at an instant of time while flow concept gives the values over a period of time.
What IS STOCK Concept and flow concept?
Stock concept doesn't have a time reference whereas Flow concept has time reference i.e. Stock concept gives the value at an instant of time while flow concept gives the values over a period of time.
What is the difference between time cycled and flow cycled ventilator?
In a time-cycled ventilator, the breath is delivered for a set period of time, regardless of patient effort, while in a flow-cycled ventilator, the breath is delivered until a preset flow rate is reached. Time-cycled ventilation is independent of the patient's respiratory effort, whereas flow-cycled ventilation is dependent on the patient's inspiratory effort.
What is the relation between flow discharge and time?
Flow discharge is the volume of water passing through a specific point in a river or stream in a given amount of time. The relationship between flow discharge and time is that flow discharge is typically measured in cubic meters per second or cubic feet per second, indicating the volume of water passing a point per unit time. As time increases, the cumulative flow discharge over that period also increases.
What is a flow weighted average?
A flow weighted average is found by dividing the total load over the estimation time by the total stream flow.
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.
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.
