What is Flow work: Definition and 15 Discussions

In positive psychology, a flow state, also known colloquially as being in the zone, is the mental state in which a person performing some activity is fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity. In essence, flow is characterized by the complete absorption in what one does, and a resulting transformation in one's sense of time.
Named by Mihály Csíkszentmihályi in 1975, the concept has been widely referred to flow state across a variety of fields (and is particularly well recognized in occupational therapy), though the concept has been claimed to have existed for thousands of years under other names.The flow state shares many characteristics with hyperfocus. However, hyperfocus is not always described in a positive light. Some examples include spending "too much" time playing video games or becoming pleasurably absorbed by one aspect of an assignment or task to the detriment of the overall assignment. In some cases, hyperfocus can "capture" a person, perhaps causing them to appear unfocused or to start several projects, but complete few.
Other related concepts include trance, hypnosis, hypomania and mindfulness.

    How does this Promise program flow work in javascript?

    Promises syntax that I learnt: let p = new Promise(function (resolve, reject) { let x = 20, y = 20; if (x == y) { resolve(); } else { reject(); } })p.then(function () { console.log("that's correct"); }) .catch(function () { console.log("that's not correct"); }) I...

    Understanding Constant Temperature in Ideal Gas Filling Process

    I'm trying to solve a problem where a perfect ideal gas is entering an initially evacuated rigid vessel. The input pressure and temperature are Pi and Ti which are constant. The incoming mass Mi is an arbitrary function of time. When i solve this, i get the temperature inside the container as...

    Kinetic Energy vs Flow Work: Exploring the Difference

    As per work energy principle, the energy spent in moving an object is stored as kinetic energy.Flow work is done to make the fluid move.Why is it not included in kinetic energy (i.e) why kinetic energy and flow work are considered seperately?

    Are flow work and work done during isobaric expansion similar?

    In case of isobaric expansion, the system expands at constant pressure(the external pressure i.e. the resistance is constant.).In case of flow work, the fluid trying to exit the control volume, pushes against the pressure at the exit of the control volume or when entering the control volume, the...

    Can't understand how flow work is possible in a control volume

    I am struggling to fully grasp the concept of flow work for a non-deformabable control volume. Nearly every source puts it in this way: flow work is the work required to push fluid into and out of the control volume and as such is defined as Pv on a unit mass basis. But how can this work be...

    Pressure in Flow Work (u + Pv)

    Why is the pressure used in flow work the pressure of the fluid? If the fluid was say at 10kPa and the external pressure was at 0Pa, why don't we use the 0Pa in our calculations for flow work, since it's the external pressure that's the resistance? Or is it not possible to have this difference...

    Flow work and kinetic energy in fluid flow

    Considering horizontal flow in a pipe (under the action of pressure forces only) if we focus on a fluid element we have a pressure gradient across the same i.e, a net pressure force will always act over the element that essentially maintains the flow.Now, in a region in the flow field if the...

    Flow Work vs PdV Work: Is PdV Valid for Both Closed & Open Systems?

    Hello friends, Referring to the attachment it can be clearly understood that flow work in an open system is a form of the PdV work defined as the boundary work or displacement work for a closed system. Does that mean PdV work is valid for both a closed system and an open system?

    Why does using Conventional Flow work?

    Hello, I've recently started reading about circuits. It was going good until I got to the idea of Conventional Flow. It confused me so I googled it and I can understand that people are used to it and scientists didn't know what an electron was when they thought about what was going on in...

    Global emergent time, how does Tomita flow work?

    Tomita time is an intrinsic observer-independent time variable available to us for fully general relativistic analysis. As far as I know it is the only such time available for things like general covariant statistical mechanics GC statistical quantum mechanics GC quantum field theory Here I...

    What is the difference between flow work and kinetic energy?

    Hi I was wondering, for the first law most books have basically Q - W = deltaUsystem + deltaH + deltaKE + deltaPE. Assuming steady state and negligible PE change, we just have deltaH and deltaKE. I was wondering, since H includes flow work (in the form of PV), why is KE still part of the...

    Why is Flow Work defined as pV and not pdV?

    In the chapter relative to First law applied to flow processes, my book explains the "Flow Work" which appears in the energy balance, as work needed to push a volume of fluid into (and out of) the control volume. It also says that it's equal to pV, and then it is added to the internal energy U...

    Using Enthelpy to define flow work for a non-ideal gas

    For an open system with mass flowing in and out, where mass exits the system there is work associated with the mass transport. When this work is used to say, push up a piston, this is pretty intuitive, but even when it does not lift a weight since, the force COULD be used to lift a weight, it is...

    Flow work and the first law of thermodynamics

    Hi Im trying to understand the justification for flow work for a control volumen considering the 1. law of thermodynamics. \[\begin{array}{l} \frac{d}{{dt}}(me) + \sum {{{(e\dot m)}_{out}}} - \sum {{{(e\dot m)}_{in}} = \dot Q + \dot W} + {{\dot W}_{fw}}\\ {{\dot W}_{fw}} = \sum...
