“…Apart from conventional methods of the determination of density of a liquid, several alternative methods have been developed by different researchers with different approaches. Amongst them Koenigs [1] and Hughes [2] used a method for measuring density in which the volume of the body must be known. Hughes [3] experimentally proved that the method of suspension of a substance inside a liquid gives most accurate value of volume than any other method using Archimedes' principle.…”

A cost-effective method has been developed with utmost efficiency for the determination of density of a liquid. The experimental setup for this purpose is a Polyvinyl chloride (PVC) cylinder fitted with an overflow spout, a volume measuring cylinder, a wooden block along with a hook and a known mass taken from scientific weight box. For this purpose, a PVC cylinder is filled up to the neck of the over flow spout with the liquid whose density is to be measured. A wooden block along with the hook is entered gently inside the cylinder, so that the wooden block along with the hook floats inside the liquid. As a result, some liquid will overflow through the overflow tube, and is collected in the volume measuring cylinder. The volume of the measuring cylinder is noted. Now the wooden block along with the hook is taken out from the liquid and a known mass from the weight box is fixed with the hook. The PVC cylinder again filled up with the liquid up to the neck of the overflow tube and put gently the wooden block fixed with the known mass by the hook inside the liquid. The fixed mass is such that the mass with the block floats inside the liquid, as a result some liquid will overflow again through the overflow tube and is collected in the volume measuring cylinder. The volume is recorded. This volume will be greater than the earlier one. From differences of volume and the mass associated with the block the density of the liquid used can easily be determined.

“…Usually, at the physics laboratory, a simple experiment can be done by measuring the weight of a body completely immersed in a fluid by using a commercial dynamometer and/or a scale [5,6]. Then the buoyant force is calculated by the dif ference between the weight in air and the weight of the body completely immersed, it is also called apparent immersed weight.…”

The study of buoyancy becomes very interesting when we measure the apparent weight of the body and the liquid vessel weight. In this paper, we propose an experimental apparatus that measures both the forces mentioned before as a function of the depth that a cylinder is sunk into the water. It is done using two load cells connected to an Arduino. With this experiment, the student can verify Archimedes' principle, Newton's third law, and calculate the density of a liquid. This apparatus can be used in fluid physics laboratories as a substitute for very expensive sensor kits or even to improve too simple approaches, usually employed, but still at low cost.

“…Density is defined as mass per unit volume, i.e., density = mass/volume, so to calculate the value of density of an object, its mass and volume are measured. In 1984 Koenigs [1] described a method for measuring liquid density. This is based on the principle that the buoyant force exerted by a liquid on an immersed body is counterbalanced by the downward force on the vessel.…”

A simple method, which is based on the principle of moment of forces only, is described for the determination of the density of liquids without measuring the mass and volume. At first, an empty test tube and a solid substance, which are hung on each side of a metre rule, are balanced and the moment arm of the test tube is measured. Keeping the solid substance in the same position, the test tube is filled with a liquid of known density up to a mark and then balanced. The moment arm is measured. Then the test tube is filled with the unknown liquid (whose density is to be determined) up to that mark and after balancing the moment arm is measured. By measuring these three moment arms and using the density of the known liquid, the density of the unknown liquid is determined.
