One more...Neutral is not supposed to carry any current or
voltage.
Earth wire will carry current, voltage in case of short
circuit.

Answer / ivy

Earth is a search current for dissipation
Neutral is the reference point for current also the return
path for current

Answer / j.krishnamoorthy

NEUTRAL is a return path of current in single phase loads.
However in a balanced three phase loads NEUTRAL will not
carry any current. In case of unbalanced three phase load
conditions NEUTRAL will carry algebraic sum of all three
phase currents.

EARTH wire is connected to a metallic body (non-live) parts
of a machine. In case of insulation failure EARTH wire will
act as a return path, to protect humans from electric shock.
For better protection, resistance of EARTH wire is
maintained below 5 ohms.

Answer / alfaz

Earthing is always a zero voltage plane ,whereon the neutral
is at a ground zero potential or it can be some non zero
potential.

diff between neutral ,ground,phase , earthing and shielding?

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
