A simple U-tube that is open at both ends is partially lled with a liquid of density 775 kg/m3. Water is then poured into one arm of the tube, forming a column 9.2 cm in height, as shown in the diagram. light liquid 775 kg/m3 heavy liquid 1000 kg/ m3 What is the difference in the heights of the two liquid surfaces? The density of heavy liquid is 1000 kg/m3. Answer in units of cm. A simple U-tube that is open at both ends is partially lled with heavy liquid.
