The report provides a speculative analysis of the turbine technology proposed for use at Swansea Bay Tidal Lagoon. The analysis incudes an evaluation of the methods of calculation of the flow of power as well as the variables required in the calculation. The report will in addition cover the concept of the effect of decreasing or increasing the number of turbines in the generation of power.

A turbine is a machine, which converts rotational energy from a particular fluid, picked by a rooter mechanical system into usable energy or work. The fluid can be water, gas or wind. Turbine technology is the technology applied in the transformation of the rotational energy into usable energy. Swansea Bay has the capacity to produce energy from the sea tides. In this case, there will be an application of the hydro turbine technology, which will make use of the impulse turbine in consideration of the volume and the flow of the water (Lewis, Neil, Robins, & Hashemi, 2015).

The evaluation of the amount of power produced has two primary considerations; namely, head and flow of water. The flow is the amount of water redirected to move the turbine generator (Rehman, Al-Hadhrami, & Alam, 2015). The head is the average distance the fluid will fall on its way to the generator. The magnitude of the flow is directly proportional to the volume of water and the head. A low head site is 10 meters while a high head site is 20 meters. The head site depends generally on the depth of the water. The primary equation in the evaluation of power is:
Power = Head x Flow x Gravity.
Another approach to calculate power is use an Automatic Hydro Power Calculator in calculating the flow in a turbine. The equation for rate of flow of water is
Flow rate = Power/ (turbine efficiency x density of water x acceleration due to gravity)
Thereby;
Power = turbine efficiency x water density x acceleration due to gravity x head

The turbines are the primary elements used in the transformation of water into useful energy. An increase in the number of turbines will significantly lead to an increase in the overall power generated by the station. In this case, many turbines will increase the turbine efficiency thus which leads to an increase in the whole process of production of power. An increase in the number of turbines also increases the general rate of flow of water through the system thus leading to an increase in the power generated.

A decrease in the number of turbines will adversely reduce the overall power output. In this case, the turbine efficiency decreases. Given that turbine efficiency is proportional power it leads to a successive decrease in the generation of power (Williamson, Stark, & Booker, 2014). The volume of water determines the number of turbines used. As the water or the tides have some form of pressure, application of several and efficient turbines will lead to an increase in the general production of power. In the case of the length of the turbines, longer turbines lead to an increase in the power produced while shorter turbines decrease the generation of power.

Power is directly proportional to the efficiency of turbines, water density, acceleration, and head. The type of technology adopted in any station depends on the depth of the water, the head and the volume of water in the speculated area. An increase in the number of turbines will increase the output energy while a decrease in the number of turbines will decrease the amount of power generated.
