4) A gold coin weighs 0.30478 N in air. The gold coin submerged in water weighs 0.01244 N. The density of water is 1000kg/m³. The density of gold is 19.3 x 10³ Kg/m³. Is the coin made of pure gold? 5) 10 m³/hour of water flows through a 100 mm diameter pipe. Determine the velocity of water if the pipe is reduced to 80 mm in diameter?
