Use the coefficient of volume expansion to estimate the density of water as it is heated from 60°f to 130°f at 1 atm. compare your result with the actual density (from the appendices). the density of water at 60°f and 1 atm pressure is ρ1 = 62.36 lbm/ft3. the coefficient of volume expansion at the average temperature of (60 + 130)/2 = 95°f is β = 0.187 × 10–3r–1. the change in density due to the change of temperature from 60°f to 130°f at constant pressure is – lbm/ft3. the approximation is
