Neha @ Siva
this is the defination of the 1 Ampere,Sir i want to know
why coulomb is choosen as fundamental Quantity ?
Is This Answer Correct ? | 5 Yes | 1 No |
Current is flow of electrons/charge with respect to time i.e.,
6.241 × 10^18 electrons, or one coulomb passing through a
conductor in one second is called 1 Ampere. 1 Ampere = 1
coulomb/sec

Answer / narendra mishra
amperes can be broken down
into coulombs and seconds, the coulomb cannot be broken
down (except to a
specific count of electrons or protons). Why does there
seem to be some
contradiction between the definition of a fundamental
quantity (a quantity
that can't be described in terms of another quantity)

Working principle capacitance type level transmitter
Calculate the maximum pressure drop that can be allowed to occur across a control valve, so that we can prevent cavitation / flashing from occurring. Use the following formula: Δ P allow = Km (P1 – PvapourA) where, Δ P allow - the maximum allowable differential pressure for sizing purposes, or terminal pressure drop; Km- the valve recovery coefficient from the manufacturer’s catalogue; P1 - absolute inlet fluid pressure; PvapourA - absolute fluid vapour pressure at the inlet temperature; Use Atmospheric pressure = 101.3 kPa, P1 = 1200 kPa(g), PvapourA = 4 kPa, KM = 0.72
