Question

What is water Equivalent ??

Answer 1

The mass of water that would have
the same heat capacity as a given
. It is numerically equal to the
product of the body's mass and its
specific heat capacity.
Water equivalent, (W)= mc
where m = mass of the body and
c = specific heat of the body. Its SI
unit is kg.

Answer 2

Water equivalent of a substance is that the quantity of water that may absorb identical quantity of warmth because the substance per degree rise in temperature.

Explanation: {the quantity|the number|the quantity} of warmth that raises the temperature of some substance by some amount, identical amount of warmth that may raise identical temperature of a definite mass of water; the mass of water is then referred to as water equivalent.

The heat absorbed or lost by a substance = water equivalent of the substance × temperature increase or decrease.

For example, if we are saying the water equivalent of a substance is twentymetric weight unit, we tend to perceivethat the warmth that's needed to boostthe temperature of the substance by 1°C is wont to raise the temperature of twenty metric weight unit of water by 1°C.

The heat capability and water equivalent each area unit capable the merchandiseof the mass of a substance and heat energy. so their numerical values area unit equal. however the units area unitcompletely different. By heat capabilitywe tend to mean some quantity of warmth whereas by water equivalent we tend to mean some mass of water.
