No. Most water meters are of the positive displacement type. They meter actual volume, and are pressure independent. Also note that water flow and pressure are not the same thing. You can have high flow with low pressure, and also low flow with high pressure, depending on the size of the pipe and/or openings (such as valves) and the pressure.
yes
The unit for electrical 'pressure' is the volt. It is measured with a voltmeter.
it depends on what your dealing with, room pressure is found with a barometer, to measure pressure in a flowing fluid, you can use a manometer. there are many variou ways to find pressure, but you must be specific on the circumstances
its the amount of constant pressure produce in cylinders pistons which make work equal to actual cycle work
Isobars are not measured. An isobar describes a part of a thermodynamic process during which the pressure doesn't change. It is also used as a term in graph tables where it describes the behavior of a material at a constant pressure.
That depends on what basis you want to calculate it - in other words, what information is provided. You could try to measure the heat that goes out. Or, if you use a heating element that uses a certain power (in watts), then - assuming, as you did, that the internal temperature remains constant - the heat flowing out is equal to the power used by the heating element.
I suppose your looking for Pressure, Volume and Temperature, all related in the equation P∙ V ÷ T is constant.
A reference point is part of the definition of movement or displacement. The difference, over time, of your distance or orientation to a given reference point or points defines movement.
Usually the instrument used is called a barometer- which could be a closed end manometer or an aneroid barometer.An altimeter actually also measures atmospheric pressures - but for a different purpose.
I believe it is experiment on Bernoulli's principle that use conservation of energy to calculate velocity or flow of the incompressible fluid. It is stated Total Pressure = static Pressure at reference height + momentum + potential height See attachment for experiment detail.
Amperage.
Ammeters measure the current flowing through a circuit
