Viscosity varies with temperature. Specific weight: each fluid has a characteristic density. Water, which is used as a term of comparison, conventionally has a specific gravity (or density) 1 (at 4 C and at sea level). The specific weight represents the value used to compare the weight of a certain volume of liquid with the same amount of water weight.
