Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substance as long as the chemical composition is the same for all phases. These substances mainly have a constant/ uniform composition. The substances also have fixed boiling and melting points. A pure substance takes part in a chemical reaction to form predictable products.

Hydro Tasmania has initiated the Battery of the Nation (BotN) strategic initiative to investigate and map out future development opportunities for the State of Tasmania to make a bigger contribution to a future National Electricity Market (NEM). The Tarraleah scheme redevelopment pre-feasibility study was undertaken through this initiative, with funding support from ARENA under the Advancing Renewables Program. For this assignment problem you will be using your knowledge of hydro power to: (1) estimate extended specifications for a new power station on the left bank of the Nive River opposite the existing power station; and (2) to reverse engineer specifications for the Pelton turbines currently installed at the Tarraleah power station. The pre-feasibility design team established basic parameters of a new power station to comprise two Francis turbines with a design flow of 20 m³/s (total 40 m³/s), a net head of 305 m and an installed capacity of ~57 MW (total 113 MW). The Tarraleah…
