The Águas Livres Aqueduct ( Portuguese: Aqueduto das Águas Livres, pronounced [ɐkɨˈðutu ðɐz ˈaɣwɐʒ ˈlivɾɨʃ], "Aqueduct of the Free Waters") is a historic aqueduct in the city of Lisbon, Portugal. It is one of the most remarkable examples of 18th-century Portuguese engineering. The main course of the aqueduct covers 18 km, but ...
Portuguese Water Dogs rode in fishing trawlers as they worked their way from the Atlantic waters of Portugal to the waters off the coast of Iceland fishing for cod. [2] In Portuguese, the breed is called cão de água ( IPA: [ˈkɐ̃w dɨ ˈaɣwɐ]; literally 'dog of water'). In Portugal, the dog is also known as the Algarvian Water Dog ( cão ...

The Museu da Água ( Water Museum) is located in Lisbon, Portugal. [1] The museum, the former steam pumping station of Barbadinhos, Lisbon, built in 1880, is in a 19th-century industrial building. The museum features four large steam engines dating from 1880. One has been reconditioned as a working demonstration. The pumps were in use until 1928.
Up to a temperature of 0.01 °C, the triple point of water, water normally exists as ice, except for supercooled water, for which one data point is tabulated here. At the triple point, ice can exist together with both liquid water and vapor. At higher temperatures, the data are for water vapor only.
The SPC/E model adds an average polarization correction to the potential energy function: = (), where μ is the electric dipole moment of the effectively polarized water molecule (2.35 D for the SPC/E model), μ 0 is the dipole moment of an isolated water molecule (1.85 D from experiment), and α i is an isotropic polarizability constant, with a value of 1.608 × 10 −40 F·m 2.
