n: the value of current or voltage at any given instant in a cycle of an AC circuit.

n: used to reduce current or voltage to a known proportion of that in the circuit. A meter is attached to the reduced voltage or current and the voltage or current in the circuit is computed from the meter reading.

a flange with plastic gasket and bolt isolation devices to stop electrical conductance.

n: the inlet filter that lie to the intake of pumps water pipe..

n: an orifice meter with an automatic integrating device. It is constructed so that the product of the square roots of the differential and static pressures is recorded on the chart. The products are continuously totaled and shown on a counter index. When the product total is multiplied by the orifice flow constant, the rate of flow is determined directly.

n: a pressure-multiplier-type well servicing mobile pump.

a pressure multiplier device use to assist pumping in high pressure well work.

a perforating gun effect in which the firing of charges overlap slightly with the effect of one charge affecting the development of a jet in another with the result of reduced penetration.

n: (lMCO) an international organisation that regulates maritime practices, including possible pollution of the oceans by tanker-cleaning effluent. Later became International Maritime Organisation.

n: the mud sheath that exist in hole pores.

filtration control by particles smaller than the pore bridging size that invade the pores and bridge within the pore throats. Often very difficult to remove.

n: a heat engine in which the pressure necessary to produce motion of the mechanism results from the ignition or burning of a fuel-air mixture within the engine cylinder.
