Don't think so - all my references show it's to do with air pressure in constricted flow. Check you question. You are correct. The Venturi effect has nothing to do with light. It is the ability to create positive and negative pressures with various tubes. Siphons work on a venturi principle for example.
The force that causes turgor pressure is osmosis.
Actually when the flow emerges from the throat area of venturi to enter into the diverging section, their is a negative pressure gradient i.e, in layman terms fluid is trying to flow from low pressure region to high pressure region according to Bernoulli equation. In this adverse pressure gradient, there is boundary layer separation, in simple terms, the fluid leaves the surface of the wall. Due to this there can be energy loss or the fluid can't recover the pressure fully leading to head loss. So if divergent section is long that means more gradual diverging section, due to which the adverse pressure gradient is less so less chance of boundary separation and hence less loss. Also large diverging section will ensure proper development of flow, i.e. fluid sticking to the wall back after separation.
The loss of electrons.
An increase in beaker pressure causes an increase in glomerular pressure.
The discharge coefficient is near unity and Non-recoverable net head loss is very small.
The water will boil when the fluid gets hot. Steam in the fluid will causes a loss of hydraulic pressure.
A venturi is also called a "jet pump", an "injector", or an "eductor". As a fluid velocity is increased, its pressure decreases. A venturi is sued to increase fluid velocity, to obtain the lower pressures necessary to draw in some other fluid. Commonly used to drain water beds using flow from a sink, to add chemicals to a water stream, and to add gasoline to an air stream (in older engines).
All kinds of things can cause loss of pressure. We need real facts to figure out why- Please resubmit with more information about your water supply.
carefully
its not, the orifice headloss is higher because the change is abrupt.
The flow of air in the carburetor venturi is restricted.
That depend where the pressure is dropping. Possibly a plugged valve under the sing where pressure loss is seen, or possibly a leak under the floor, especially if piped with Poly-B.
What is a Venturi?
difference in air pressure at the venturi throat and the air inlet.
