Voltage drop means reduction of voltage.Additional AnswerAccording to Kirchhoff's Voltage Law, the sum of the voltage drops around any closed loop within a circuit must equal the value of the supply voltage. So, no, a voltage drop is not a 'lost' voltage, as the circuit's supply voltage is accounted for when you add up all the voltage drops (including any internal voltage drop within the source itself).
The voltage drop across an LED varies, but is typically around 2 volts.
A device for dividing the flow into the valve between two outlets. The spool is pressure balanced by the flow across it. When a greater pressure drop occurse at one of the ports the spool moves across to counteract this and divert more flow to one side. They are not perfectly accurate.
It is used to measure the rate of flow of liquid & glasses
If there is less voltage across a resistor, there will also be less current.As for the second question, I assume you mean two resistors in series. If the voltage or potential difference across one decreases, then the other one must increase, due to Kirchhof's Voltage Law: the total voltage across the two resistors must be equal to the voltage across the battery, which is usually assumed to be constant.AnswerYou can think of voltage drops in terms of a water radiator central heating system. In order to drive water around all the radiators, there must be a difference in pressure across the entire system. But for water to flow through each, individual, radiator, there must also be a difference in pressure across its input and output orifices. The sum of these individual pressure difference must equal the pressure difference across the entire system.If you now equate a pressure difference across an individual radiator with the voltage drop across a resistor, then the sum of the voltage drops across each resistor must equal the voltage across the entire circuit.You should also realise that voltage does not 'slow down' current -it affects its magnitude (in amperes)
to create annular area so that the diff. pressure can be kept constant.
the orifice plate creates a restriction in the pipeline which creates a pressure drop across the plate. commonly found in high pressure relief systems or drain points (as this would usually be a HP/LP interface) and can also be used to measure flow, by measuring the pressure drop across the plate.

Pressure Drop - song - was created in 1970.
Use a delta-p gauge
Pressure Drop - album - was created in 1975-11.
The cavitaion index across a valve or pipe fitting is defined as the ratio of difference between upstream pressure and vapor pressure to the pressure drop across the valve or fitting. The index at which incipient cavitation, damage, or choked flow occurs is based on testing and depends on the type of valve or fitting.
Rotameter
The float in rotameter is lifted by the liquid. Rotameter is calibrated for particular liquid or gas with its exact density. if we mount it horizontally float will not come to its original place.
The voltage drop across an LED varies, but is typically around 2 volts.
To read a rotameter, look at the position of the float inside the tube. The flow rate is indicated on the scale where the float is positioned. The number on the scale closest to the center of the float is the flow rate being measured.
