What is density of water? 64.4 Lb/ft3 What is value of g 9.81 m/s2 What is relation between Density and Specific Weight Specific weight shouldn't be confused with density P=density, slugs/ft3 g=acceleration due to gravity. Define specific gravity? What is Specific gravity of water The specific gravity is the ratio of the density of a substance total density of water, the specific gravity of water is 1.000 n/m^3. What is the Weight of 1.0 cubic foot of water? 62.4 lbs What is specific gravity of Kerosene, which has a specific weight of 7.85 times 10^3 N/m^3? A reservoir of water is connected to a 12 in. diameter pipe 50 feet long and capped at the end. The water surface elevation of the reservoir is 82.5 ft and capped end of the pipe is at elevation 38 ft. Find the pressure in psf at the capped end of the pipe. 2776.8
