A cylindrical tank with a diameter of 80 cm is partially filled with SAE l0 W oil (p = 870 kg/ ). Ifche mass of the oil in the tank is 340 kg, determine the height of the oil in the tank.

An overhead tank has length, width and height of 2 m, 2.5 m, and 1.5 m, respectively. If the water is filled up to three-quarters of its height, determine the mass and weight of the water inside the tank.
