Ohms law states that when current is flowing through the any conductor then current is directly proportional to the voltage universally proportional the resistance if temperature is constant.
Bernoulli theoram state that total energy flowing from the one point to another point remains constant its generally used in non compressible liquids.
Charles law if the pressure and the amount of gas remain constant the volume of the gas increase or decrease by the same factor as its temperature.
Pascal law pressure change occurring any where in the fluids.

Can we use thermocouple in generator of power station replace RTD(pt 100)? if we don't have any place for use RTD.

if we open the inlet of an air regulator ,how it will affect the out put of regulator? (out put of regulator is using to operate an on-off valve.it is an air to open valve,and valve is in open position.my doubt is air regulator will hold the valve in open or not,if there is no consumption or leak in regulator out put side ,we only loose the input pressure.)
