The specificweight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a materialSpecificweightofwater at standard sea-level atmospheric pressure (metric units)[2]. Example 5: SpecificWeightofWater.The density ofwater is 1.940 slugs/ft3 at 39 °F (4 °C). The specificweight in Imperial units is. Specific Gravity = weightof substance / weightofwater. Physicists use a reference temperature of 4°C (539.2°F) for specific gravity.Specific Gravity and Density ofWater at Atmospheric Pressure* (Weights are in vacuo). The specificweightofwater (or sometimes called the "unit weight"), `gamma_W`, at standard temperature and pressure (STP) is approximately 62.31lb/(`ft^2 * s^2`) and is computed as the density ofwater at STP * the gravitational constant, g. Related Mcqs: Specificweightof sea water is more that of pure water because it contains _?A piece of wood having weight 5 kg floats in water with 60% of its volume under the liquid. The density ofwater is 1000 kg/m^3 (or 1 g/cm^3). But you're right that it does vary a little bit with temperature. Georgia, US Mostly Asked From. The specificweightofwater is 62.4 lb/ft3.b. Determine the weightof 1 L ofwater, in N. The density ofwater is calculated as 1000 kg/m³, and using its density, the density and specificweightof mercury are found to be 13560 kg/m³ and 133,081.6 N/m³ respectively. SpecificWeightofWater.
