A mining company depleted more than half of its ore reserves and is no longer using all of its shaft infrastructure. It considers using one of the old shafts for pumped-storage hydro-electricity generation. This means that water will be pumped to the higher level, which is 1 000 m above the bottom level, at night when Eskom charges lower, off-peak, rates. The “higher level” will be changed into a dam (reservoir) by means of plugs that will be installed in some tunnels. The stored water has potential energy, which will be used to generate electricity for the mine at peak hours, when electricity is expensive. The pump that will be installed at the bottom of the column will also be used as a turbine for the generation of electricity The pump-as-turbine (PAT) must pump water to a height of 1 000 m through a column with an internal diameter (ID) of 345 mm. 3.1. Calculate the velocity of the water in the pipe if the quantity of water to be pumped is 220 litres per second (lps). 3.2.…
How is the energy loss captured by the apparatus? You may explain using mathematical equations. Bernoulli's Apparatus
Havard University campus has 200 classrooms and 400 faculty offices. The classrooms are equipped with 12 fluorescent tubes, each consuming 110 W, including the electricity used by the ballasts. The faculty offices, on average, have half as many tubes. The campus is open 240 days a year. The classrooms and faculty offices are not occupied an average of 4 h a day, but the lights are kept on. If the unit cost of electricity is $ 0.082/kWh, determine how much the campus will save a year if the lights in the classrooms and faculty offices are turned off during unoccupied periods.
