Find specific weight of an unknown liquid.
The U-tube manometer shown to the right is used to measure the exact weight of a liquid. The manometer tube has an internal diameter of 0.5cm and it is initially filled with water. Accurately 2 cm3 of an unknown liquid is after that poured into one leg of the manometer, and a displacement of 5 cm between the surfaces is measured as shown. What is the specific weight of the unknown liquid?
