What is the turbine output of 100m head and delivering 1 cu. m/ sec in a hydro electric power plant if turbine efficiency is 88%?
A hydro - electric power station has a reservoir of area 2.4 square kilometres
and capacity 5x10°m.The effective head of water is 100 m. The penstock, turbine
and generator efficiencies are 95%, 90%, and 85% respectively.
(i)Calculate the total energy in kWh which can be generated from the power station.
(ii)If a load of 15,000 kW has been supplied for 3 hours, find the fall in reservoir level.
A remote community in Marikina plans to put up a small hydro-electric plant to service six closely located barangays estimated to consume 52,650,000 KW-hrs per annum. Expected flow if water is 1665 m³/min. The most favorable location for the plant fixes the tail water level at 480 m. The manufacturer of turbine generator set have indicated the following performance data: turbine efficiency 87%; generator efficiency is 92%; loss in head work not exceed 3.8% of available head. In order to pinpoint the most suitable area for the dam, determine the head water elevation in m.
