Question

1.Identify the phase transition occurring. The water level in an aquarium tank falls continuously (the tank has no leak).

Answer 1

One thing that is important in determining whether you need (or even want) to get a sump for your home aquarium is whether your fish tank is an open or closed system.

Most aquariums are closed systems. In a closed system, there is no place for water to leak out. Canister filters, ultra-violet sterilizers, and fluidized bed filters are all closed systems. Water is taken out of the fish tank through a tube, pumped through the sterilizer or filter, and returned to a point inside the tank. This is called a closed system because there isn't any point along the water's path where it is not controlled and contained. Closed systems do not need a sump.

Open systems have some means within the system where water could - or is even expected to - escape. Trickle filters and protein skimmers are open systems. These pieces of equipment are designed with openings to allow the release of water, air, or waste. Because these systems are open, they need something to catch the water that can (or does) pass through. Though they can be set up so that this can fall back into the tank, usually it is the sump that catches this overflow.

The coninuous in-tank leak detection system is a comprehensive automatic tank-gauging and leak-detection system that can simultaneously monitor product levels, water levels, temperatures and leaks in up to 8 tanks. With advanced technology, enhanced features and intelligent software, the continuous in-tank leak detection system is suitable for a variety of continuous automatic tank gauging and leak-detection monitoring.
