1. A new town is being developed in a rural area of Costa Rica. Planners are projecting a population of about 2,000 people and a baseload electric energy demand for the town of 10MWe over the first 20 years. A nearby river flows from the rainforest region with a mean annual flow of 100m³/s. Over a 20 km distance upstream of the town site, the river has a change in elevation of 1,000 m. Seasonal variations in the river flow could be as large as a factor of ten above or below the mean flow. Is a hydro project using turbines with 80 % efficiency feasible to meet the town's future energy needs? Discuss (2-3 sentences each) at least two associated impacts that planners also need to consider in the hydro project design.

1.3 Mention at least four steps to be taken when applying Bernoulli's equation. 1.4 Ibika campus has water tanks installed around the campus to try and mitigate the water crisis. At the department of mechanical engineering there is a water tank installed on the ground floor. The tank has a pipe 600 m connected to it which carries water to the upper tank 10 m high. In between there is a centrifugal pump which pumps the water to the upper floor. The pump works with a maximum head of 16 m. Make a neat arrangement of the system and write down Bernoulli's equation for this system.

A multipurpose reservoir with a surface area of 1 km² is being designed for Gibson, TN. The daily average inflow from a nearby stream is 0.05 m³/s. Annual precipitation averages 1400 mm/yr and losses to evaporation and seepage to groundwater are expected to be 500 mm/yr. A minimum daily release of 0.01 m³/s is required to protect downstream fisheries. Assuming the volume of the lake is 107,000 m³, how long will it take to fill the reservoir?
