# How do you Calculate volume of water in a closed loop using the pumps gpm?

Take the gpm of the recirculating pump and multiply by 10/2.4 equal system volume. This is used to estimate expansion tanks. It good plus or minus 10% depending on new additions

### How can you calculate the volume of an object with only the knowledge of the density?

You cannot calculate the volume of an object using only the density; you must also calculate the mass. You can calculate the mass by simply weighing the object. Density = Mass / Volume Therefore Volume = Mass/Density. If you cannot be bothered to calculate the mass, simply measure the object. Multiply the length, times the width, times the height and you have the volume.

### How do you calculate the density of a non-uniform object?

The density of a non-uniform object can be found by using its mass and volume. The volume can be measured by placing the object in volumetric glassware filled with water. The increase in volume is equal to the volume of the object. The object can then be weighed using a scale. The density of the object will be given by the ratio of mass / volume.

### How do you get ice's density?

Using the formula density = mass/volume. Take one ice cube, quickly weigh it, and then drop it into a measuring cylinder already filled with a quantity of water. record the change in volume, which is the volume of the ice cube. To calculate the density, calculate as follows: mass of ice cube / volume = density in grams/cm3
